THE ARMADILLO REPEAT REGION FROM MURINE BETA-CATENIN
Overview
Beta-catenin is essential for cadherin-based cell adhesion and, Wnt/Wingless growth factor signaling. In these roles, it binds to, cadherins, Tcf-family transcription factors, and the tumor suppressor gene, product Adenomatous Polyposis Coli (APC). A core region of beta-catenin, composed of 12 copies of a 42 amino acid sequence motif known as an, armadillo repeat, mediates these interactions. The three-dimensional, structure of a protease-resistant fragment of beta-catenin containing the, armadillo repeat region has been determined. The 12 repeats form a, superhelix of helices that features a long, positively charged groove., Although unrelated in sequence, the beta-catenin binding regions of, cadherins, Tcfs, and APC are acidic and are proposed to interact with this, groove.
