a tumor suppressor. Defects in APC are a cause of familial adenomatous polyposis (FAP). Promotes rapid degradation of CTNNB1 and participates in Wnt signaling. Activity is correlated with its phosphorylation state. Two splice-variant isoforms have been described. Note: This description may include information from UniProtKB.
Protein type: Motility/polarity/chemotaxis; Tumor suppressor
Molecular Function: beta-catenin binding; cadherin binding; gamma-catenin binding; identical protein binding; microtubule binding; microtubule plus-end binding; protein binding; protein kinase binding; protein kinase regulator activity; ubiquitin protein ligase binding
