General description

Catenin α is a novel actin-binding and -bundling protein. Catenin α is responsible for organizing and tethering actin filaments at the zones of E-cadherin-mediated cell-cell contact. Monomeric Catenin α can bind strongly to E-Cadherin-β-Catenin, whereas the dimer preferentially binds actin filaments. Different molecular conformations are associated with these different binding states, indicating that Catenin α is an allosteric protein. Catenin α directly regulates actin-filament organization by suppressing Arp2/3-mediated actin polymerization, likely by competing with the Arp2/3 complex for binding to actin filaments

Frauke Drees et al.
Cell, 123(5), 903-915 (2005-12-06)
Epithelial cell-cell junctions, organized by adhesion proteins and the underlying actin cytoskeleton, are considered to be stable structures maintaining the structural integrity of tissues. Contrary to the idea that alpha-catenin links the adhesion protein E-cadherin through beta-catenin to the actin
D L Rimm et al.

Calcium-dependent homotypic cell-cell adhesion, mediated by molecules such as E-cadherin, guides the establishment of classical epithelial cell polarity and contributes to the control of migration, growth, and differentiation. These actions involve additional proteins, including alpha- and beta-catenin (or plakoglobin) and
