p130 Cas Phospho-Regulation Antibody Kit
Antibody Sampler Kit
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.

Western blot analysis of human endothelial cells serum starved overnight (lanes 1, 3, & 5) or treated with pervanadate (1 mM) for 30 minutes (lanes 2, 4, & 6). The blot was probed with anti-p130 Cas (PM1441; lanes 1 & 2), anti-p130 Cas (Tyr-751) (PP1581; lanes 3 & 4), or anti-p130 Cas (Tyr-762) (PP1451; lanes 5 & 6).
Western blot analysis of A431 cells serum starved overnight (lanes 1 & 3) or treated with pervanadate (1 mM) for 30 minutes (lanes 2, 4-6). The blot was probed with anti-p130 Cas (lanes 1 & 2) or anti-p130 Cas (Tyr-762) (lanes 3-6). The latter was used in the presence of no peptide (lane 4), phospho-p130 Cas (Tyr-762) peptide (lane 5) or phospho-p130 Cas (Tyr-751) peptide (lane 6).
