Predicted to enable kinase binding activity and phosphotyrosine residue binding activity. Predicted to be involved in several processes, including cell surface receptor protein tyrosine kinase signaling pathway; endothelin receptor signaling pathway; and positive regulation of peptidyl-serine phosphorylation. Predicted to act upstream of or within lens morphogenesis in camera-type eye. Predicted to be located in focal adhesion and membrane. Orthologous to human BCAR3 (BCAR3 adaptor protein, NSP family member); INTERACTS WITH 2,3,7,8-tetrachlorodibenzodioxine; 2,4-dinitrotoluene; 6-propyl-2-thiouracil.
