Catenin beta-1

The distinct peripheral cytosolic proteins, alpha, beta and gamma-catenin (102, 94 and 86 kD) found in many tissues (1,2,3) 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. (6,7) They are good candidates for mediating transduction of cell-cell contact positional signals to the cell interior. (4,5) Absence of alpha-catenin is found in certain tumor cell lines (8) and reduced levels in certain human carcinomas (9). 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. (10) This interaction involves a 15-aa repeat in the APC. (11) Beta-catenin cell levels seem to be controlled by APC. (12) The central core region of beta-catenin is involved in mediation of cadherin-catenin complex interaction with EGFR. (13)
