Predicted to enable non-membrane spanning protein tyrosine kinase activity. Predicted to be involved in B cell receptor signaling pathway; adaptive immune response; and peptidyl-tyrosine autophosphorylation. Predicted to act upstream of or within apoptotic process; cell adhesion; and phosphorylation. Predicted to be located in nucleoplasm and ruffle membrane. Is expressed in several structures, including cardiovascular system; central nervous system; immune system; lung; and mammary gland. Orthologous to human BMX (BMX non-receptor tyrosine kinase).
