The initial review preserves all eight normally seeded source dictionaries, covering nine raw QuickGO records. Two dated ISS records project to the same stored DynAP assertion and are collapsed by the existing ETL, not by manual curation. Three localization rows are accepted; five assembly rows are refined to outer and inner arm assembly. There are five official predicted products, one integrated assembly core and no NEW annotation.
Human respiratory-cell dynein-arm loss, zebrafish phenotypes and Chlamydomonas rescue/complex experiments in PMID:22387996 establish the assembly work. The full original Methods were read separately from the incomplete normal cache. In particular, Figure 7 HA-IC2 co-immunoprecipitation retains HCα/β with reduced HCγ in pf22; the phenotype is not absence of all heavy/intermediate-chain association. Chlamydomonas inner arm f is retained. Tagged PF22 localization is algal; no human localization experiment or universal isoform function is inferred.
The DynAP donor is literal Xenopus Q32NQ7, with direct IDA from PMID:30561330. Original Figure 2C and the Methods on Xenopus cDNA cloning/imaging provide the positive source evidence. The human supplemental staining targets other proteins. Actual PAINT descent and the family/SL mappings are verified. Current IBD and QuickGO donor lists differ in the presence of zebrafish; both support the same node/terms, and neither donor count nor target experimental grounding is treated as circularity.
The independent core consultation and owner source review agree on a single outer/inner dynein-arm maturation unit. PMID:38261620 strongly supports the candidate arginine methyltransferase model through structure and algal mutant proteomics. PMID:39969973 provides comparative limits and explicitly unresolved catalytic versus noncatalytic assembly mechanisms. A purified-human or catalytic-dead rescue experiment is not reported in these evaluated sources. The candidate mechanism remains in the biological description and a BIOLOGY knowledge gap; no precise type-II activity, direct motor activity or autonomous chaperone function is assigned.
Five official product sequences were independently reconstructed. Named isoform 2 is accession Q8N9W5-5 and has a predicted NMD caution. Product -6 is a 47-residue N-terminal extension, so historical Leu108 corresponds to canonical Leu61. Historical numbering and sequence compatibility are not natural-product functional equivalence.
Falcon authentication and perplexity-lite quota failures are documented; no provider report was invented. Genuine normal caching ultimately succeeded for the newer primary papers after retained rate-limit failures. PMID:30561330 is an exact reuse of a genuine normal cache shared with the DNAAF11/DNAAF2 work. Existing main sources, machine outputs and the frozen bootstrap remain unchanged. ROOT performs final canonical validation, status, rendering, history and publication.

DNAAF3 helps produce assembly-competent dynein components of motile cilia. Human patient respiratory cilia lack outer and inner arms, while zebrafish morphants can retain ciliary projections with largely normal number and morphology but defective arms and motility. In Chlamydomonas, genomic rescue restores assembly, and heavy/intermediate-chain immunoprecipitation shows abnormal complexes that cannot complete productive axonemal assembly. The proposed later maturation step generates an “assembly-competent complex”; chaperone release or transport competence remain mechanistic hypotheses rather than measured human activities PMID:22387996, Results/Figures 3–5 and 7, Discussion/Figure 8.
This constituent-assembly work supports the original motile-cilium assembly assertions as core biology. It does not imply that DNAAF3 builds every ciliary structure or that losing it must eliminate ciliary projections. The current motile cilium assembly definition covers aggregation and arrangement of the components. Checked is_a/part_of ancestry places outer-arm assembly and inner-arm assembly beneath axonemal dynein complex assembly, but not beneath GO:0044458. The two motile-cilium assertions are therefore retained as ACCEPT; the three axonemal-dynein assertions retain their specific two-term replacements. This supersedes the earlier five-MODIFY count: the effective eight decisions are five ACCEPT and three MODIFY, with the three assembly processes represented together in one core and no NEW assertion.
The compartment and mechanism boundaries remain distinct. Direct tagged-DNAAF3 DynAP imaging in the 2018 study is Xenopus evidence supporting the human ortholog inference, not imaging of endogenous human DNAAF3 PMID:30561330, Figure 2C and cloning/imaging Methods. Structural predictions and loss of detectable arginine-methylated dynein peptides in algal pf22 mutants support the methyltransferase model, while later comparative data leave catalytic and noncatalytic assembly contributions unresolved PMID:38261620, structural comparisons and mutant proteomics, PMID:39969973, Discussion. The existing purified-protein and catalytic-mutant experiment question remains appropriate; no intrinsic human catalytic activity or equivalence of the five natural products is added.
The two human/ortholog IMP decisions now carry separate short cache-exact assembly anchors, with the prior patient-arm anchor moved once from the core. The biological notes add only the two-word excerpt above, keeping the aggregate for PMID:22387996 at 22 words. The other three existing source excerpts are retained once. The 2012 Methods remain separately recovered original evidence because the genuine normal cache omits them; the historical notes and publication caches remain unchanged.
