Predicted to enable actin filament binding activity and beta-catenin binding activity. Predicted to be involved in cell migration and cell-cell adhesion. Predicted to act upstream of or within cell adhesion. Predicted to be located in several cellular components, including actin cytoskeleton; anchoring junction; and nucleus. Predicted to be part of catenin complex. Predicted to be active in adherens junction. Human ortholog(s) of this gene implicated in patterned macular dystrophy 2. Orthologous to human CTNNA1 (catenin alpha 1).
