Gene Description

APC is a large, multidomain tumor suppressor that coordinates beta-catenin turnover and cytoskeletal organization. Its central repeats bind beta-catenin and its SAMP motifs engage AXIN in the cytoplasmic destruction complex, helping recruit and present beta-catenin to kinases and ubiquitination machinery. Its C-terminal regions bind microtubules, associate with microtubule-end proteins and directly recruit actin monomers to nucleate filaments. These activities contribute to cell polarity, migration and accurate mitosis. APC also binds regulatory partners, including Asef-family nucleotide-exchange factors, whose autoinhibition it can relieve. APC occupies cytoplasmic, cortical, junctional and nuclear pools; truncating variants disrupt several of these separable functions and underlie familial adenomatous polyposis and many sporadic colorectal cancers.

ACCEPT
Summary: Mitotic cytokinesis fits the established APC function or location.
Reason: PMID17570218 compares APC-mutant human tissue and mouse models and uses video microscopy of cytokinesis. Retain APC involvement in mitotic division; division defects do not assign APC contractile-motor chemistry.

ACCEPT
Summary: Kinetochore fits the established APC function or location.
Reason: PMID11283619 explicitly places APC at kinetochore-embedded microtubule ends and associates it with Bub proteins. This supports the kinetochore location, separately from the unverified centrosome row.
Supporting Evidence:

KEEP AS NON CORE
Summary: Cell fate specification is supported but secondary to APC’s principal activities.
Reason: Retain the PAINT ancestral-function inference. Cell-fate effects are developmental outputs of APC-mediated Wnt regulation, rather than a separate molecular activity.

MODIFY
Summary: APC SAMP3 binds the isolated RGS-like domain of AXIN.
Reason: The original source directly resolves APC binding to the isolated AXIN RGS-like domain using SAMP3 pull-downs, an unbound GST control and the crystal complex. The official 1EMU record maps the APC peptide to human P25054 and identifies the AXIN component as human. GO:0019904 captures this experimentally defined domain-specific interaction; it does not substitute beta-catenin binding or assign APC a G-protein-regulatory activity. The normal publication cache is abstract-only; targeted original Results, figure legends and binding Methods were read separately.

Summary: Refine this source-specific assertion to PDZ domain binding.
Reason: 23185543 actual Methods/Fig1 and deposited4G69 show the human APC C-terminal peptide bound to human DLG1 PDZ2. Same-source specific binding only; no autonomous scaffold/catalytic activity, no transfer of this refinement to unread screen rows72/73.

UNDECIDED
Summary: Source-local evidence remains unresolved for protein binding.
Reason: 24251807 abstract establishes AMER3 binding to APC and to AMER1; its statement about AMER1–APC is background and does not identify the experimental APC–AMER1 pair in this paper. Retain the original source object. The unresolved point is the source-local target assay or table and its controls.

KEEP AS NON CORE
Summary: Protein binding is supported but secondary to APC’s principal activities.
Reason: PMID24251807 explicitly reports AMER3 binding the APC armadillo domain. This supports its own non-core pair, distinct from the uninspected AMER1 pair cited to the same paper.

Summary: Refine this source-specific assertion to beta-catenin binding.
Reason: This source directly characterizes an APC–beta-catenin interaction, rather than merely listing a proteomic candidate. Refine the generic interaction to beta-catenin binding while preserving its original experimental reference, partner and qualifier. Existing beta-catenin-binding rows are corroborating records, not grounds to invent another row.

Summary: Refine this source-specific assertion to beta-catenin binding.
Reason: This source directly characterizes an APC–beta-catenin interaction, rather than merely listing a proteomic candidate. Refine the generic interaction to beta-catenin binding while preserving its original experimental reference, partner and qualifier. Existing beta-catenin-binding rows are corroborating records, not grounds to invent another row.
Proposed replacements: beta-catenin binding

Reason: The current GO:0016342 definition concerns the E-cadherin/catenin actin-linkage complex. PMID7806582 explicitly distinguishes alternative APC-containing and E-cadherin-containing catenin complexes in its available abstract. The full source-local assay behind this exact IDA compartment mapping has not been inspected, so preserve uncertainty rather than treating any beta-catenin complex as sufficient.

UNDECIDED
Summary: The mouse cold-tolerance phenotype does not yet resolve APC’s specific regulatory contribution.
Reason: The complete accessible abstract reports cold intolerance, reduced brown-adipose glucose uptake and altered adipocyte morphology in Apc-min mice. The normal cache is abstract-only, and the full experimental controls were not recovered. These observations do not yet distinguish an APC regulatory contribution from secondary systemic effects; they also do not prove that tumor burden is the sole explanation. GO:0120162 describes positive regulation, so APC need not generate heat directly to participate. The mouse donor experiment and its transfer to human APC require source-local adjudication before either retention as an established function or an over-annotation judgment.
Propagation Review
Root cause: UNRESOLVED
Sources checked:
UniProtKB:Q61315 UNRESOLVED
The actual mouse-source abstract was read, but full experimental controls and the historical ISS derivation were not reconstructed. Cold intolerance alone does not resolve an APC regulatory role versus indirect disease effects; no failed transfer is asserted.

NEW
Summary: APC directly nucleates actin filaments.
Reason: APC itself recruits actin monomers and builds the nucleation seed in purified and single-molecule experiments; its formin partner performs subsequent elongation. Human full-length APC rescue with a nucleation-defective mutant separates this work from mere necessity and from microtubule binding. Parent, same-role comparator, existing-term redundancy and GO-CAM checks support this single process level; no additional actin-process descendant is proposed.

    binding of APC to microtubules increases microtubule stability in vivo and in vitro
  • PMID:11283619

Binds actin and recruits actin monomers to assemble a filament-nucleation seed. APC remains at the nucleation site while its formin partner can drive barbed-end elongation; this activity is separable from APC microtubule binding.

Suggested Questions for Experts

Q: Which unresolved interaction records establish a source-specific APC domain or regulatory mechanism, and which reflect indirect coassembly? Independent positive experiments do not establish the exact assay in an unread screen.

Q: How are APC beta-catenin destruction, microtubule organization, actin nucleation and Asef activation coordinated between cellular pools and endogenous isoforms?

Q: Which APC constructs and cellular conditions reconcile the intact-destruction-complex model with proposed component-disassembly models?

Q: What direct target-specific evidence places APC at centrosomes or in receptor-associated Wnt signalosomes, beyond movement of its partners or broad pathway membership?

Q: Would the purified human APC basic-domain filament binding and bundling reported in PMID:17293347 justify refining broad actin binding to actin filament binding (GO:0051015)? Keep monomer recruitment for nucleation distinct from filament binding, and avoid adding a redundant parent/child NEW pair without resolving their separate evidence scopes.

Suggested Experiments

Experiment: Compare matched full-length human APC and separation-of-function mutants in endogenous rescue, measuring beta-catenin turnover, actin nucleation, microtubule organization and Asef activation separately, with isoform and expression controls.
