Protein5
Adenomatous polyposis coli (APC) also known as deleted in polyposis 2.5 (DP2.5) is a protein that in humans is encoded by the APC gene. (wikipedia.org)
The (Adenomatous Polyposis Coli) APC protein normally builds a "destruction complex" with glycogen synthase kinase 3-alpha and or beta (GSK-3α/β) and Axin via interactions with the 20 AA and SAMP repeats. (wikipedia.org)
The protein localizes to the cytoplasmic microtubule network and binds APCL, a homolog of the adenomatous polyposis coli tumor suppressor gene. (nih.gov)
The adenomatous polyposis coli tumor suppressor protein is also implicated in beta-catenin signaling. (embl.de)
In the absence of Wnt signals, the cytoplasmic catenin beta-1 ( β-catenin ) is associated with a complex including auxin, glycogen synthase kinase 3 ( GSK-3 ), and adenomatous polyposis coli ( APC ) (the APC protein acts as the primary regulator of β-catenin function). (hindawi.com)
