Adenomatous polyposis coli

This article refers to the tumor suppressor APC, in which mutations lead to colon cancer. For the cell-cycle regulatory complex, APC/C, see Anaphase-promoting complex.

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. The APC protein is a negative regulator that controls beta-catenin concentrations and interacts with E-cadherin, which are involved in cell adhesion. Mutations in the APC gene may result in colorectal cancer.
