  • RelevanceThe distinct peripheral cytosolic proteins, alpha, beta and gamma-catenin (102, 94 and 86 kDa) found in many tissues bind to the conserved cytoplasmic tail domain of the cell-adhesion cadherins. Catenins link E-cadherin to other integral membrane or cytoplasmic proteins and are modulated by Wnt-1 proto-oncogene. They are good candidates for mediating transduction of cell-cell contact positional signals to the cell interior. Absence of alpha-catenin is found in certain tumor cell lines and reduced levels in certain human carcinomas. Beta-catenin binds directly to the cytoplasmic tail of E-cadherin. It binds to the N-terminus of alpha-catenin and interacts with the protein product of the tumor suppressor gene APC. This interaction involves a 15-aa repeat in the APC. Beta-catenin cell levels seem to be controlled by APC. The central core region of beta-catenin is involved in mediation of cadherin-catenin complex interaction with EGFR.

  • Western blot of ab52227 detecting alpha 1 catenin protein. Mouse small intestine epithelial cells were isolated and run on a 9% denaturing gel. The gel was blocked with 5% milk for 1 hour before being incubated with ab52227 (1:1000) for 12 hours at 4°C in 5% Milk/TBS Tween. The antibody was detected using anti-rabbit IgG conjugated to HRP (1:2500).  Lane 1 is an intestinal epithelial lysate taken from a conditional Adenomatous Polyposis Coli (APC) mutant mouse, while lane 2 was taken from a control.
