Background

P130 Cas (Crk-associated substrate (CAS), breast cancer antiestrogen resistance 1 (BCAR1) ) is a docking protein containing multiple protein-protein interaction domains. The N-terminal SH3 domain functions as a molecular switch regulating CAS tyrosine phosphorylation, as it interacts with tyrosine kinases and phosphatases. The C-terminal Src binding domain contains a proline-rich motif that mediates interaction with the SH3 domains of Src-family kinases (SFKs) . Phosphorylation of this domain at Tyr-762 in rat (Tyr-668 in mouse) promotes this interaction. The p130 Cas central substrate domain is characterized by 15 tyrosines present in Tyr-X-X-Pro (YXXP) motifs, including Tyr-165, Tyr-249, and Tyr-410. When phosphorylated, most YXXP motifs are able to serve as docking sites for proteins with SH2 or PTB domains. In addition, phosphorylation of Tyr-751 (Tyr-653 in human) near the C-terminal caspase recognition site can attenuate caspase cleavage, while dephosphorylation occurs during apoptosis and may facilitate p130 Cas degradation.

Immunogen

Phospho-p130 Cas (Tyr-762) synthetic peptide (coupled to KLH) corresponding to amino acid residues around tyrosine 762 in the Src-binding domain of rat p130 Cas. This rat sequence is the same as Tyr-664 in human p130 Cas and Tyr-668 in mouse p130 Cas. This site is also highly conserved in Cas-L (HEF1, Nedd9) .

Specificity

This antibody was cross-adsorbed to phospho-tyrosine coupled to agarose and to phospho-p130 Cas (Tyr-751) peptide before affinity purification using phospho-p130 Cas (Tyr-762) peptide (without carrier) . The antibody detects a 130 kDa* protein corresponding to the molecular mass of phosphorylated p130 Cas on SDS-PAGE immunoblots of pervanadate treated human A431 cells, but not in control cells.
