Claim: SOCE-induced Pyk2, a member of the FAK subfamily of protein tyrosine kinases,has been shown to bind a CRK-associated substrate, a nephrocystin, a GTPase regulator associated with FAK, and the SH2 domain of GRB2.
Evidence: The encoded protein is a member of the FAK subfamily of protein tyrosine kinases but lacks significant sequence similarity to kinases from other subfamilies. This protein has been shown to bind a CRK-associated substrate, a nephrocystin, a GTPase regulator associated with FAK, and the SH2 domain of GRB2.
