Predicted to enable beta-catenin binding activity and protein C-terminus binding activity. Predicted to be involved in several processes, including Rho protein signal transduction; activation of GTPase activity; and negative regulation of protein localization to cell surface. Predicted to act upstream of or within negative regulation of cell population proliferation. Predicted to be located in actin cytoskeleton; cytoplasm; and fibrillar center. Orthologous to human TAX1BP3 (Tax1 binding protein 3). [provided by Alliance of Genome Resources, Apr 2022]
