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.
