AAAS encodes ALADIN, a WD-repeat scaffold nucleoporin of the nuclear pore complex. ALADIN is anchored at the nuclear envelope through NDC1 and contributes to normal NPC-associated nucleocytoplasmic transport, especially in tissues affected by triple-A syndrome such as adrenal, gastrointestinal, and neural systems. In mitosis, ALADIN also localizes to spindle structures and helps spatially regulate inactive Aurora A and downstream spindle factors, supporting robust spindle formation and chromosome alignment.

nuclear pore

IBA
GO_REF:0000033 |
ACCEPT |
Summary: AAAS/ALADIN is a nuclear pore complex nucleoporin. Disease-associated ALADIN variants lose NPC targeting, and NDC1 anchoring is required for ALADIN localization at the nuclear envelope.
Reason: The nuclear pore annotation is a central, well-supported cellular component for AAAS. The PN nuclear-pore projection also agrees with existing GOA, but it adds no new term beyond this already captured location.
Supporting Evidence:
PMID:12730363
ALADIN localizes to nuclear pore complexes (NPCs), large multiprotein assemblies that are the sole sites of nucleocytoplasmic transport.
PMID:19782045
We identified NDC1 but not GP210 and POM121 as the main anchor of ALADIN within the NPC.

nucleocytoplasmic transport

IBA
GO_REF:0000033 |
ACCEPT |
Summary: ALADIN is an NPC-associated protein implicated in normal nucleocytoplasmic transport rather than gross NPC structure. Existing IBA/NAS/IDA transport rows are consistent with the disease-mutant mislocalization evidence and NPC biology.
Reason: Nucleocytoplasmic transport is more informative and better scoped for AAAS than the PN-projected broad parent protein transport. I retain this existing transport term and do not add GO:0015031 protein transport from the PN projection.
Supporting Evidence:
PMID:12730363
We propose that ALADIN plays a cell type-specific role in regulating nucleocytoplasmic transport and that this function is essential for the proper maintenance andor development of certain tissues.

spindle pole

IEA
GO_REF:0000044 |
ACCEPT |
Summary: ALADIN localizes to mitotic spindle structures, including the spindle pole, in the AURKA/spindle study.
Reason: The mitotic localization is experimentally supported and functionally tied to ALADIN-dependent spatial regulation of Aurora A. This is a genuine AAAS role, distinct from but compatible with its NPC identity.
Supporting Evidence:
PMID:26246606
Without ALADIN, Aurora A spreads from centrosomes onto spindle microtubules, which affects the distribution of a subset of microtubule regulators and slows spindle assembly and chromosome alignment.
PMID:26246606
ALADIN interacts with inactive Aurora A and is recruited to the spindle pole after Aurora A inhibition.

Summary: Nuclear envelope/nuclear membrane localization is consistent with ALADIN being an NPC nucleoporin anchored through NDC1.
Reason: This cellular component is well supported by ALADIN-specific localization and anchoring evidence. For the HPA-derived nuclear membrane row, the term is less specific than nuclear pore but still consistent with the NPC location at the nuclear envelope.
Supporting Evidence:

ACCEPT |
Summary: The original structural NPC-scaffold source has only abstract text available locally, but independent ALADIN-specific evidence supports nuclear-envelope/NPC localization.
Reason: Retain the nuclear envelope annotation because ALADIN is directly shown to be anchored in the nuclear envelope via NDC1. The unavailable original full text limits direct assessment of the 2013 structural study details, so the review also relies on ALADIN-specific localization evidence.
Supporting Evidence:
PMID:24315095
The nuclear pore complex (NPC) is a fundamental component of all eukaryotic cells that facilitates nucleocytoplasmic exchange of macromolecules.
PMID:19782045
Based on our findings we conclude that ALADIN is anchored in the nuclear envelope via NDC1 and that this interaction gets lost, if ALADIN is mutated.

Summary: The HPA-derived nucleoplasm signal is plausible for an NPC-associated protein but is less specific than nuclear pore/nuclear envelope localization.
Reason: AAAS should primarily be represented as a nuclear pore/nuclear envelope component. Nucleoplasm localization may reflect immunofluorescence signal or cell-state context and is not the best descriptor of the core site of action.

REMOVE |
Summary: This protein binding row comes from a TMEM18 study that reports interaction with NPC components. It does not define a specific AAAS molecular function.
Reason: GO:0005515 protein binding is too generic for curation and the source is primarily about TMEM18 biology. The finding may identify AAAS as an NPC component/interactor, but that context is already captured by nuclear pore and nucleocytoplasmic transport annotations.
Supporting Evidence:
PMID:28811369
We provide evidence that TMEM18 has four, not three, transmembrane domains and that it physically interacts with key components of the nuclear pore complex.

Summary: The PGRMC2 interaction with ALADIN is experimentally supported, but protein binding is uninformative as a GO molecular-function annotation.
Reason: The interaction should be retained as biological evidence in the notes/reference findings, not as the generic GO:0005515 term. No more specific AAAS molecular-function term is supported strongly enough from this interaction alone.
Supporting Evidence:
PMID:27754849

Summary: ALADIN is observed at the nuclear envelope/perinuclear region in adrenal-cell interaction experiments with PGRMC2.
Reason: This is consistent with the core NPC/nuclear-envelope localization of AAAS. The PGRMC2 paper supports nuclear-envelope localization and an interaction context, but it should not be inflated into a specific transport or steroidogenesis GO process for AAAS.
Supporting Evidence:
PMID:27754849
We detected that PGRMC2 co-localises with ALADIN and with different FG-repeat NUPs [stained with anti-NPC proteins (mAb414)] to the nuclear envelope and the perinuclear ER.
PMID:19782045
Based on our findings we conclude that ALADIN is anchored in the nuclear envelope via NDC1 and that this interaction gets lost, if ALADIN is mutated.

Summary: ALADIN localizes to mitotic spindle structures, including the spindle pole, in the AURKA/spindle study.
Reason: The mitotic localization is experimentally supported and functionally tied to ALADIN-dependent spatial regulation of Aurora A. This is a genuine AAAS role, distinct from but compatible with its NPC identity.
Supporting Evidence:
PMID:26246606
Without ALADIN, Aurora A spreads from centrosomes onto spindle microtubules, which affects the distribution of a subset of microtubule regulators and slows spindle assembly and chromosome alignment.

ALADIN interacts with inactive Aurora A and is recruited to the spindle pole after Aurora A inhibition.

Summary: ALADIN depletion produces shorter, less robust spindles and affects spindle microtubule organization.
Reason: The phenotype supports a role in spindle organization, but microtubule bundle formation is a less direct and less informative description than mitotic spindle assembly/AURKA localization. Keep the row as non-core supporting phenotype rather than the main process term.
Supporting Evidence:
PMID:26246606
Without ALADIN, Aurora A spreads from centrosomes onto spindle microtubules, which affects the distribution of a subset of microtubule regulators and slows spindle assembly and chromosome alignment.

Summary: AAAS was detected in a high-throughput membrane proteomics study, but generic membrane localization is much less informative than nuclear envelope/nuclear pore.
Reason: The term is not strictly false because the NPC is embedded in the nuclear envelope, but this HDA row loses the important nuclear-pore context and the source study includes many proteins predicted to be transiently associated with membranes.

Summary: AAAS was detected in a sperm nucleus proteomics data set, but generic nucleus localization is broader than the established nuclear pore/nuclear envelope site.
Reason: The nucleus term is broadly compatible with an NPC protein but over-generalizes the curated AAAS localization. Nuclear pore and nuclear envelope should be preferred for functional interpretation.

The specific Reactome events range across viral transport, mRNA/tRNA transport, SUMOylation, and disease pathways and should not be used to infer those pathway processes for AAAS without separate gene-level evidence.
Supporting Evidence:
PMID:19782045
Based on our findings we conclude that ALADIN is anchored in the nuclear envelope via NDC1 and that this interaction gets lost, if ALADIN is mutated.

Summary: ALADIN is an NPC-associated protein implicated in normal nucleocytoplasmic transport rather than gross NPC structure. Existing IBA/NAS/IDA transport rows are consistent with the disease-mutant mislocalization evidence and NPC biology.
Reason: Nucleocytoplasmic transport is more informative and better scoped for AAAS than the PN-projected broad parent protein transport. I retain this existing transport term and do not add GO:0015031 protein transport from the PN projection.

Q: Should AAAS be annotated to a more specific nuclear protein import/export term only if future gene-level evidence identifies affected protein cargos, rather than adding the broad PN-projected GO:0015031 protein transport?
Suggested experts: Cronshaw JM, Matunis MJ, Kind B, Huebner A
Q: Is the ALADIN-PGRMC2 association functionally upstream of adrenal steroidogenesis in vivo, or should it remain an interaction note without a GO process annotation?
Suggested experts: Juehlen R, Koehler K, Huebner A
Experiment: Perform quantitative nuclear/cytoplasmic proteomics or live import/export reporter assays in AAAS-null and rescue human adrenal/neural cell models, with cargo-level validation for candidate proteins.
Hypothesis: ALADIN loss selectively alters nuclear import or export of stress-response or DNA-repair proteins in adrenal and neural cell types.
Type: nucleocytoplasmic transport assay
Experiment: Compare steroidogenic enzyme activity, PGRMC2 localization, and CYP-dependent steroid output in AAAS knockout, NDC1-anchoring-defective rescue, and wild-type rescue adrenocortical cells.
Hypothesis: The ALADIN-PGRMC2 interaction has a specific steroidogenic consequence rather than representing proximity at the perinuclear ER/NPC.
Type: functional rescue and steroidogenesis assay
The research report should be a detailed narrative explaining the function, biological processes, and localization of the gene product. Citations should be given for all claims.
You should prioritize authoritative reviews and primary scientific literature when conducting research. You can supplement
this with annotations you find in gene/protein databases, but these can be outdated or inaccurate.
We are specifically interested in the primary function of the gene - for enzymes, what reaction is catalyzed, and what is the substrate specificity? For transporters, what is the substrate? For structural proteins or adapters, what is the broader structural role? For signaling molecules, what is the role in the pathway.
We are interested in where in or outside the cell the gene product carries out its function.
We are also interested in the signaling or biochemical pathways in which the gene functions. We are less interested in broad pleiotropic effects, except where these elucidate the precise role.
Include evidence where possible. We are interested in both experimental evidence as well as inference from structure, evolution, or bioinformatic analysis. Precise studies should be prioritized over high-throughput, where available.
This report concerns human AAAS, which encodes the nucleoporin ALADIN (UniProt accession Q9NRG9), a 546–amino-acid WD-repeat protein localized to the nuclear pore complex (NPC); this identity is consistently stated in recent peer-reviewed literature and matches the UniProt target context provided. (ruizbabot2023generationofglucocorticoidproducing pages 12-14, hasenmajer2023rareformsof pages 9-10)
AAAS/ALADIN is best understood as a non-enzymatic WD-repeat scaffold nucleoporin that supports selective nucleocytoplasmic trafficking of specific protein cargoes and/or regulators at the NPC, with downstream consequences for DNA repair capacity, nuclear protection from oxidative damage, and adrenal steroidogenic signaling. Pathogenic biallelic variants cause triple A (Allgrove) syndrome, classically featuring alacrima, achalasia, and primary adrenal insufficiency, often with neurological/autonomic involvement. (cehic2024veryearlyand pages 1-3, ruizbabot2023generationofglucocorticoidproducing pages 12-14, smits2024biallelicndc1variants pages 8-10)
ALADIN is described as a WD-repeat nucleoporin localized to the NPC, where WD repeats (seven described in recent sources) are interpreted as forming a protein–protein interaction scaffold rather than conferring catalytic activity. (ruizbabot2023generationofglucocorticoidproducing pages 12-14, ruizbabot2023generationofglucocorticoidproducing pages 3-4)
Functional definition (gene product role): rather than transporting metabolites or catalyzing reactions, ALADIN’s primary functional annotation is NPC-associated regulation/enablement of selective nuclear import/export of specific proteins, which can produce tissue-specific phenotypes when disrupted. (cehic2024veryearlyand pages 1-3, ruizbabot2023generationofglucocorticoidproducing pages 12-14)
A major advance in current mechanistic understanding is the clear emphasis that ALADIN’s correct localization at the NPC/nuclear envelope is NDC1-dependent. Recent work summarizes that ALADIN is anchored via the transmembrane nucleoporin NDC1 (rather than POM121/GP210) and that disruption of this interaction reduces ALADIN nuclear-envelope recruitment. (smits2024biallelicndc1variants pages 11-12, smits2024biallelicndc1variants pages 8-10)
A 2024 study in Human Genetics and Genomics Advances provides direct cellular evidence: fibroblasts carrying pathogenic NDC1 variants show reduced ALADIN localization to the nuclear envelope and a measurable defect in post-mitotic NPC insertion/assembly. (smits2024biallelicndc1variants media 042ddde5, smits2024biallelicndc1variants pages 5-7)
Recent reviews and mechanistic syntheses highlight selective nuclear import failure affecting:
- DNA ligase I and aprataxin (DNA single-strand break repair proteins). (braun2026pathologiesatthe pages 10-12, cehic2024veryearlyand pages 1-3, ruizbabot2023generationofglucocorticoidproducing pages 12-14)
- Ferritin heavy chain (FTH1), which is discussed as protective against nuclear oxidative damage; impairment of its nuclear import is used to support an oxidative-damage mechanism. (braun2026pathologiesatthe pages 10-12, smits2024biallelicndc1variants pages 8-10, ruizbabot2023generationofglucocorticoidproducing pages 12-14)
Collectively, these findings frame ALADIN as an NPC component required for nuclear access of genome-maintenance and oxidative-protection factors in relevant cellular contexts. (braun2026pathologiesatthe pages 10-12, cehic2024veryearlyand pages 8-9)
Smits et al. (Oct 2024; https://doi.org/10.1016/j.xhgg.2024.100327) report biallelic NDC1 variants that interfere with ALADIN binding and associate with neuropathy and a triple A–like syndrome, underscoring that disruption of ALADIN recruitment can arise from genes beyond AAAS itself. (smits2024biallelicndc1variants pages 8-10, smits2024biallelicndc1variants pages 5-7)
Quantitative cellular evidence in this work includes a reduction in CDT1-positive NPC density in patient cells versus controls (mean 4.05 vs 4.58 pore/mm²; p < 0.002), supporting impaired post-mitotic NPC insertion/assembly. (smits2024biallelicndc1variants pages 5-7)
Bitetto et al. (Jun 2023; https://doi.org/10.1186/s13023-023-02763-w) examined postmortem adrenal tissue from an AAAS-mutant patient and reported:
- Reduced ALADIN in total lysate and membrane fraction with slight cytosolic increase (consistent with altered localization/fractionation).
- Reduced SCARB1 transcript, reduced MC2R (ACTH receptor) immunoreactivity, and phospho-PKA mislocalization (reduced nuclear, increased cytosolic fractions), suggesting impaired ACTH/cAMP signaling and transcriptional activation of steroidogenic pathways. (bitetto2023scarb1downregulationin pages 4-6, bitetto2023scarb1downregulationin pages 6-8, bitetto2023scarb1downregulationin pages 1-2)
These findings provide a concrete, human-tissue-supported mechanism connecting an NPC protein defect to adrenal steroidogenic failure. (bitetto2023scarb1downregulationin pages 6-8)
Ruiz-Babot et al. (Nov 2023; https://doi.org/10.1016/j.crmeth.2023.100627) developed human pluripotent stem cell–derived steroidogenic cells and used CRISPR-engineered AAAS knockout and an AAAS truncation model to recapitulate triple A adrenal insufficiency phenotypes. (ruizbabot2023generationofglucocorticoidproducing pages 1-3, ruizbabot2023generationofglucocorticoidproducing pages 21-23)
In this system, AAAS/ALADIN loss is associated with reduced steroid output: KO and mutant lines secrete significantly lower cortisol, cortisone, corticosterone, and aldosterone than controls (measured by ELISA and LC–MS), and a block at 11β-hydroxylation (CYP11B enzymes) is described as a mechanistic bottleneck. (ruizbabot2023generationofglucocorticoidproducing pages 12-14)
The functional site of action is the nuclear envelope at nuclear pore complexes, where ALADIN is recruited/anchored by NDC1, and where its loss or mislocalization is repeatedly emphasized as a pathogenic feature in triple A syndrome. (smits2024biallelicndc1variants pages 11-12, cehic2024veryearlyand pages 1-3, ruizbabot2023generationofglucocorticoidproducing pages 12-14)
A key visual demonstration of ALADIN’s NPC localization dependence is shown in Smits et al. 2024 (Figure 4), where immunofluorescence indicates reduced ALADIN nuclear-envelope recruitment in patient fibroblasts with NDC1 variants, along with quantification of reduced post-mitotic NPC density. (smits2024biallelicndc1variants media 042ddde5)
A widely cited mechanistic model is that ALADIN disruption causes selective nuclear import defects for specific proteins (DNA ligase I, aprataxin), plausibly elevating DNA damage burden in susceptible tissues. (braun2026pathologiesatthe pages 10-12, cehic2024veryearlyand pages 1-3)
ALADIN dysfunction is repeatedly connected to oxidative stress susceptibility, supported by discussions of ferritin heavy-chain nuclear import defects and increased cellular reactive oxygen species in patient-derived contexts. (cehic2024veryearlyand pages 8-9, cehic2024veryearlyand pages 5-6, smits2024biallelicndc1variants pages 8-10)
Two complementary 2023 lines of evidence connect AAAS/ALADIN to adrenal dysfunction:
1) Human adrenal tissue findings show reduced SCARB1 and MC2R and altered phospho-PKA localization, suggesting impaired ACTH/cAMP/PKA-driven transcriptional control of steroidogenic capacity. (bitetto2023scarb1downregulationin pages 6-8, bitetto2023scarb1downregulationin pages 1-2)
2) iPSC-derived steroidogenic cell modeling shows reduced secretion of multiple adrenal steroids (glucocorticoids and mineralocorticoids) in AAAS-deficient cells. (ruizbabot2023generationofglucocorticoidproducing pages 12-14, ruizbabot2023generationofglucocorticoidproducing pages 3-4)
Together, these place AAAS/ALADIN within a mechanistic chain: NPC disruption → altered nuclear signaling/transport → dysregulated steroidogenic gene expression and enzymatic steps → adrenal insufficiency. (bitetto2023scarb1downregulationin pages 6-8, ruizbabot2023generationofglucocorticoidproducing pages 12-14)
Genetic testing for AAAS is central to confirming triple A syndrome, and recent clinical reviews emphasize that neurological involvement can be common and heterogeneous, making molecular confirmation important for management and family counseling. (cehic2024veryearlyand pages 1-3, hasenmajer2023rareformsof pages 9-10)
Smits et al. (2024) extends real-world implementation by highlighting that “triple A–like” phenotypes can result from NDC1 variants that disrupt ALADIN recruitment, implying that patients negative for AAAS mutations may warrant evaluation of ALADIN-anchoring machinery. (smits2024biallelicndc1variants pages 8-10)
The 2023 iPSC-derived steroidogenic cell system provides a practical platform for studying AAAS-associated adrenal insufficiency and for testing interventions in a human-relevant context, addressing limitations of mouse models that may not recapitulate the full human phenotype. (ruizbabot2023generationofglucocorticoidproducing pages 15-16, ruizbabot2023generationofglucocorticoidproducing pages 12-14)
Recent clinical-review literature references antioxidant approaches (e.g., N-acetylcysteine) as exploratory strategies consistent with oxidative stress models, although robust clinical trial evidence is not established in the provided sources. (cehic2024veryearlyand pages 5-6)
Authoritative recent reviews emphasize that although ALADIN’s precise molecular function is not fully resolved, convergent evidence supports roles in nucleocytoplasmic transport of selected proteins, redox homeostasis, and adrenal steroidogenesis—with mislocalization of mutant ALADIN from NPC to cytoplasm recurring as a key pathogenic theme. (cehic2024veryearlyand pages 1-3, hasenmajer2023rareformsof pages 9-10, ruizbabot2023generationofglucocorticoidproducing pages 12-14)
Cehic et al. (Sep 2024; https://doi.org/10.3389/fendo.2024.1431383) summarize clinical frequencies:
- Alacrima: >90% (also stated as “above 90%”).
- Achalasia: 75–85%.
- Primary adrenal insufficiency: almost 85%.
- Complete triad: about 70%.
- Neurological involvement: about two-thirds (also described as ~60% in the same review). (cehic2024veryearlyand pages 1-3, cehic2024veryearlyand pages 4-5)
Hasenmajer et al. (Feb 2023; https://doi.org/10.1007/s11154-023-09784-7) report:
- Fewer than 50 families described (reflecting rarity).
- AAAS variants in ~90% of patients.
- A literature review recorded 74 AAAS variants.
- Achalasia in most cohorts around 75–85%, with onset ranging from months to adolescence. (hasenmajer2023rareformsof pages 9-10, hasenmajer2023rareformsof pages 8-9)
Smits et al. (Oct 2024; https://doi.org/10.1016/j.xhgg.2024.100327) report reduced post-mitotic NPC density in patient fibroblasts (4.05 vs 4.58 pore/mm²; p < 0.002) and show reduced ALADIN nuclear-envelope localization in patient cells. (smits2024biallelicndc1variants pages 5-7, smits2024biallelicndc1variants media 042ddde5)
The following table summarizes key functional-annotation facts, mechanisms, and recent sources.
| Aspect | Key findings for human AAAS/ALADIN (UniProt Q9NRG9) | Strongest evidence type | Representative recent source(s) |
|---|---|---|---|
| Verified molecular identity | AAAS encodes ALADIN, a 546-aa WD-repeat nucleoporin of the nuclear pore complex (NPC); recent reviews/methods papers describe 7 WD repeats and broad expression with enrichment in adrenal/pituitary/CNS/GI-related tissues, matching the UniProt human target Q9NRG9 rather than another gene symbol usage (hasenmajer2023rareformsof pages 9-10, ruizbabot2023generationofglucocorticoidproducing pages 12-14) | Review; iPSC/model background | Hasenmajer et al., Feb 2023, Rev Endocr Metab Disord, https://doi.org/10.1007/s11154-023-09784-7 (hasenmajer2023rareformsof pages 9-10); Ruiz-Babot et al., Nov 2023, Cell Reports Methods, https://doi.org/10.1016/j.crmeth.2023.100627 (ruizbabot2023generationofglucocorticoidproducing pages 12-14) |
| Primary localization | ALADIN localizes to the NPC/nuclear envelope; proper NE/NPC targeting is NDC1-dependent. NDC1 variants that disrupt the ALADIN-binding region reduce ALADIN recruitment to the NE, and ALADIN is reported as anchored via NDC1 rather than POM121/GP210 (smits2024biallelicndc1variants pages 11-12, smits2024biallelicndc1variants pages 5-7, smits2024biallelicndc1variants media 042ddde5) | Structural/cell assay with patient fibroblasts | Smits et al., Oct 2024, Hum Genet Genomics Adv, https://doi.org/10.1016/j.xhgg.2024.100327 (smits2024biallelicndc1variants pages 11-12, smits2024biallelicndc1variants pages 5-7, smits2024biallelicndc1variants media 042ddde5) |
| Key interaction partner: NDC1 | NDC1 is the principal membrane anchor recruiting ALADIN to the NPC; structural modeling places NDC1 C-terminal residues in direct interface with ALADIN, and disease-associated NDC1 alleles impair ALADIN localization and NPC assembly/post-mitotic insertion (smits2024biallelicndc1variants pages 8-10, smits2024biallelicndc1variants pages 5-7) | Structural modeling + patient fibroblast assay | Smits et al., Oct 2024, https://doi.org/10.1016/j.xhgg.2024.100327 (smits2024biallelicndc1variants pages 8-10, smits2024biallelicndc1variants pages 5-7) |
| Other NPC-related partners | Recent literature also places ALADIN in a network including NUP155 in addition to NDC1; proteomic/NPC studies support ALADIN as a bona fide NPC component mislocalized in triple A syndrome (smits2024biallelicndc1variants pages 8-10, braun2026pathologiesatthe pages 23-24) | Review; NPC interaction mapping | Smits et al., Oct 2024, https://doi.org/10.1016/j.xhgg.2024.100327 (smits2024biallelicndc1variants pages 8-10); Braun et al., Apr 2026, https://doi.org/10.1007/s00018-026-06220-2 (braun2026pathologiesatthe pages 23-24) |
| Cargoes/processes affected: DNA repair proteins | A key mechanistic model is selective nuclear import failure: mutant ALADIN reduces nuclear import of DNA ligase I and aprataxin, proteins needed for repair of DNA single-strand breaks, linking AAAS dysfunction to genome maintenance defects (braun2026pathologiesatthe pages 10-12, cehic2024veryearlyand pages 1-3, ruizbabot2023generationofglucocorticoidproducing pages 12-14) | Mechanistic review of primary studies | Cehic et al., Sep 2024, Front Endocrinol, https://doi.org/10.3389/fendo.2024.1431383 (cehic2024veryearlyand pages 1-3); Ruiz-Babot et al., Nov 2023, https://doi.org/10.1016/j.crmeth.2023.100627 (ruizbabot2023generationofglucocorticoidproducing pages 12-14) |
| Cargoes/processes affected: ferritin heavy chain | ALADIN dysfunction also impairs nuclear import of ferritin heavy chain (FTH1), a protective factor against nuclear oxidative damage; this supports the widely cited model that oxidative stress susceptibility is central to AAAS pathology (smits2024biallelicndc1variants pages 8-10, braun2026pathologiesatthe pages 10-12, cehic2024veryearlyand pages 8-9, smits2024biallelicndc1variants pages 11-12, ruizbabot2023generationofglucocorticoidproducing pages 12-14) | Cell/mechanistic assay summarized by recent review | Smits et al., Oct 2024, https://doi.org/10.1016/j.xhgg.2024.100327 (smits2024biallelicndc1variants pages 8-10, smits2024biallelicndc1variants pages 11-12); Cehic et al., Sep 2024, https://doi.org/10.3389/fendo.2024.1431383 (cehic2024veryearlyand pages 8-9) |
| Core molecular function | Best-supported current interpretation: ALADIN is a scaffold/selective transport regulator at the NPC, not an enzyme or transporter with a defined small-molecule substrate. Its primary role is to enable proper nucleocytoplasmic trafficking of selected protein cargos, thereby supporting DNA repair, redox homeostasis, and tissue-specific functions in adrenal and neural cells (braun2026pathologiesatthe pages 9-10, cehic2024veryearlyand pages 1-3, ruizbabot2023generationofglucocorticoidproducing pages 12-14) | Review synthesis + disease modeling | Cehic et al., Sep 2024, https://doi.org/10.3389/fendo.2024.1431383 (cehic2024veryearlyand pages 1-3); Ruiz-Babot et al., Nov 2023, https://doi.org/10.1016/j.crmeth.2023.100627 (ruizbabot2023generationofglucocorticoidproducing pages 12-14) |
| Redox / oxidative stress role | Multiple recent sources summarize increased ROS/oxidative stress in AAAS-deficient contexts; ALADIN loss alters oxidative-stress responses in fibroblasts/adrenal cells, and antioxidant response has been proposed as a therapeutic angle in isolated reports (smits2024biallelicndc1variants pages 8-10, cehic2024veryearlyand pages 8-9, cehic2024veryearlyand pages 5-6, cehic2024veryearlyand pages 4-5) | Case-review synthesis; cell assay summaries | Cehic et al., Sep 2024, https://doi.org/10.3389/fendo.2024.1431383 (cehic2024veryearlyand pages 8-9, cehic2024veryearlyand pages 5-6, cehic2024veryearlyand pages 4-5); Smits et al., Oct 2024, https://doi.org/10.1016/j.xhgg.2024.100327 (smits2024biallelicndc1variants pages 8-10) |
| Steroidogenesis / adrenal pathway | AAAS dysfunction is linked to adrenal steroidogenic failure. In patient adrenal tissue, SCARB1 transcript is reduced, MC2R is strongly reduced, and phospho-PKA shows decreased nuclear and increased cytosolic localization, consistent with impaired cAMP/PKA-dependent nuclear signaling and ACTH resistance (bitetto2023scarb1downregulationin pages 4-6, bitetto2023scarb1downregulationin pages 6-8, bitetto2023scarb1downregulationin pages 1-2) | Patient tissue study | Bitetto et al., Jun 2023, Orphanet J Rare Dis, https://doi.org/10.1186/s13023-023-02763-w (bitetto2023scarb1downregulationin pages 4-6, bitetto2023scarb1downregulationin pages 6-8, bitetto2023scarb1downregulationin pages 1-2) |
| Human cell disease modeling | CRISPR-engineered AAAS-null iPSC-derived steroidogenic cells recapitulate adrenal insufficiency features, showing significantly lower cortisol, cortisone, corticosterone, and aldosterone secretion than controls; this is a direct 2023 implementation for functional modeling of AAAS-associated disease (ruizbabot2023generationofglucocorticoidproducing pages 12-14, ruizbabot2023generationofglucocorticoidproducing pages 3-4, ruizbabot2023generationofglucocorticoidproducing pages 1-3) | iPSC disease model | Ruiz-Babot et al., Nov 2023, https://doi.org/10.1016/j.crmeth.2023.100627 (ruizbabot2023generationofglucocorticoidproducing pages 12-14, ruizbabot2023generationofglucocorticoidproducing pages 3-4, ruizbabot2023generationofglucocorticoidproducing pages 1-3) |
| Disease association | Biallelic AAAS variants cause triple A (Allgrove) syndrome, classically comprising alacrima, achalasia, and adrenal insufficiency, often with neurologic/autonomic involvement; ALADIN mislocalization from the NPC is a common pathogenic theme (cehic2024veryearlyand pages 1-3, hasenmajer2023rareformsof pages 9-10) | Review | Hasenmajer et al., Feb 2023, https://doi.org/10.1007/s11154-023-09784-7 (hasenmajer2023rareformsof pages 9-10); Cehic et al., Sep 2024, https://doi.org/10.3389/fendo.2024.1431383 (cehic2024veryearlyand pages 1-3) |
| Key 2023–2024 clinical statistics | Recent reviews/case analyses report: complete triad ~70%; alacrima >90% or 90–100%; achalasia 75–85%; primary adrenal insufficiency almost 85%; neurologic involvement ~60% to two-thirds; AAAS variants in ~90% of patients in one 2023 review; disease prevalence cited as about 1 in 1,000,000 in review literature (cehic2024veryearlyand pages 1-3, cehic2024veryearlyand pages 4-5, hasenmajer2023rareformsof pages 9-10, hasenmajer2023rareformsof pages 8-9, braun2026pathologiesatthe pages 9-10) | Review; case-review synthesis | Hasenmajer et al., Feb 2023, https://doi.org/10.1007/s11154-023-09784-7 (hasenmajer2023rareformsof pages 9-10, hasenmajer2023rareformsof pages 8-9); Cehic et al., Sep 2024, https://doi.org/10.3389/fendo.2024.1431383 (cehic2024veryearlyand pages 1-3, cehic2024veryearlyand pages 4-5) |
| Notable genotype/phenotype data | In a 2024 genotype-focused summary, the p.Ser263Pro AAAS variant showed neurologic manifestations in 33/34 (97.1%) carriers versus 133/172 (77.3%) in other genotypes (p = 0.006); possible Slavic founder effect noted (25/36, 69.4%) (juscinska2026neurologicalmanifestationsof pages 1-2) | Cohort/genotype-phenotype analysis | Juścińska et al., Jan 2026 reporting aggregate cohort data, https://doi.org/10.1007/s10048-025-00870-3 (juscinska2026neurologicalmanifestationsof pages 1-2) |
| Recent clinical implementation | Current real-world use is mainly molecular diagnosis and mechanistic stratification of rare disease: recent Sudanese series identified 6 AAAS mutations in 20 families/31 patients, including novel alleles, emphasizing early genetic diagnosis to prevent adrenal crises; NDC1 analysis expands differential diagnosis to triple A-like syndromes when AAAS is negative (smits2024biallelicndc1variants pages 8-10) | Case series / genetic diagnostics | Smits et al., Oct 2024, https://doi.org/10.1016/j.xhgg.2024.100327 (smits2024biallelicndc1variants pages 8-10) |
| Visual/mechanistic support from recent figure | A recent figure shows reduced ALADIN nuclear-envelope staining in NDC1-variant fibroblasts and lower post-mitotic NPC density in patient cells, visually supporting the ALADIN-at-NPC recruitment model (smits2024biallelicndc1variants media 042ddde5) | Figure-based cell assay | Smits et al., Oct 2024, Figure 4 context, https://doi.org/10.1016/j.xhgg.2024.100327 (smits2024biallelicndc1variants media 042ddde5) |
Table: This table condenses the most relevant verified facts about human AAAS/ALADIN, including identity, NPC localization, interaction partners, mechanisms, disease links, and recent 2023–2024 studies. It is designed as a quick-reference artifact for functional annotation and evidence-weighted interpretation.
Some extracted excerpts describe statistical significance or “significant” changes without providing full numeric effect sizes; therefore, this report reports quantitative values only where explicitly present in the retrieved text (e.g., NPC density metrics) and otherwise reports qualitative directionality with clear attribution.

description: 'AAAS encodes ALADIN, a WD-repeat scaffold nucleoporin of the nuclear pore complex. ALADIN is anchored at the nuclear envelope through NDC1 and contributes to normal NPC-associated nucleocytoplasmic transport, especially in tissues affected by triple-A syndrome such as adrenal, gastrointestinal, and neural systems. In mitosis, ALADIN also localizes to spindle structures and helps spatially regulate inactive Aurora A and downstream spindle factors, supporting robust spindle formation and chromosome alignment.'

reason: The term is not strictly false because the NPC is embedded in the nuclear envelope, but this HDA row loses the important nuclear-pore context and the source study includes many proteins predicted to be transiently associated with membranes.
supported_by:
- reference_id: PMID:19946888
supporting_text: The remaining species were largely involved in cellular processes and molecular functions that could be predicted to be transiently associated with membranes.

review:
summary: AAAS was detected in a sperm nucleus proteomics data set, but generic nucleus localization is broader than the established nuclear pore/nuclear envelope site.
action: MARK_AS_OVER_ANNOTATED
reason: The nucleus term is broadly compatible with an NPC protein but over-generalizes the curated AAAS localization. Nuclear pore and nuclear envelope should be preferred for functional interpretation.
supported_by:
- reference_id: PMID:21630459
supporting_text: With this approach, 403 different proteins have been identified from the isolated sperm nuclei.

summary: AAAS is correctly placed at the nuclear envelope/NPC, but the Reactome source event should be treated as location context only for this nuclear envelope row.
action: ACCEPT
reason: The Reactome row should be interpreted only as cellular-component support for AAAS/ALADIN being part of the nuclear-envelope/NPC machinery. The specific Reactome events range across viral transport, mRNA/tRNA transport, SUMOylation, and disease pathways and should not be used to infer those pathway processes for AAAS without separate gene-level evidence.

evidence_type: TAS
original_reference_id: Reactome:R-HSA-9708889
qualifier: located_in
review:
summary: AAAS is correctly placed at the nuclear envelope/NPC, but the Reactome source event should be treated as location context only for this nuclear envelope row.
action: ACCEPT
reason: The Reactome row should be interpreted only as cellular-component support for AAAS/ALADIN being part of the nuclear-envelope/NPC machinery. The specific Reactome events range across viral transport, mRNA/tRNA transport, SUMOylation, and disease pathways and should not be used to infer those pathway processes for AAAS without separate gene-level evidence.

supporting_text: Based on our findings we conclude that ALADIN is anchored in the nuclear envelope via NDC1 and that this interaction gets lost, if ALADIN is mutated.

qualifier: acts_upstream_of_or_within
review:
summary: ALADIN is an NPC-associated protein implicated in normal nucleocytoplasmic transport rather than gross NPC structure. Existing IBA/NAS/IDA transport rows are consistent with the disease-mutant mislocalization evidence and NPC biology.
action: ACCEPT
reason: Nucleocytoplasmic transport is more informative and better scoped for AAAS than the PN-projected broad parent protein transport. I retain this existing transport term and do not add GO:0015031 protein transport from the PN projection.

original_reference_id: PMID:12730363
qualifier: involved_in
review:
summary: The original ALADIN disease-mutant study explicitly proposed a regulatory role in nucleocytoplasmic transport.
action: ACCEPT
reason: This term is a conservative way to capture ALADIN as an NPC-associated regulator/support factor rather than a transport receptor or cargo-specific transporter. It is preferable to adding broad protein transport from the PN projection.

core_functions:
- description: ALADIN is a scaffold nucleoporin of the nuclear pore complex at the nuclear envelope. Its NDC1-dependent NPC anchoring supports normal NPC-associated nucleocytoplasmic transport; disease-associated variants commonly fail to target to NPCs, linking loss of NPC integration to triple-A syndrome biology.

suggested_questions:
- question: Should AAAS be annotated to a more specific nuclear protein import/export term only if future gene-level evidence identifies affected protein cargos, rather than adding the broad PN-projected GO:0015031 protein transport?
experts:
- Cronshaw JM
- Matunis MJ
- Kind B
- Huebner A
- question: Is the ALADIN-PGRMC2 association functionally upstream of adrenal steroidogenesis in vivo, or should it remain an interaction note without a GO process annotation?
experts:
- Juehlen R
- Koehler K
- Huebner A
suggested_experiments:
- hypothesis: ALADIN loss selectively alters nuclear import or export of stress-response or DNA-repair proteins in adrenal and neural cell types.
description: Perform quantitative nuclear/cytoplasmic proteomics or live import/export reporter assays in AAAS-null and rescue human adrenal/neural cell models, with cargo-level validation for candidate proteins.
experiment_type: nucleocytoplasmic transport assay
- hypothesis: The ALADIN-PGRMC2 interaction has a specific steroidogenic consequence rather than representing proximity at the perinuclear ER/NPC.
description: Compare steroidogenic enzyme activity, PGRMC2 localization, and CYP-dependent steroid output in AAAS knockout, NDC1-anchoring-defective rescue, and wild-type rescue adrenocortical cells.
experiment_type: functional rescue and steroidogenesis assay
