Detection of Human, Mouse, and Rat p130Cas by Western Blot. Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line, Neuro‑2A mouse neuroblastoma cell line, and L6 rat myoblast cell line. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human p130Cas Monoclonal Antibody (Catalog # MAB5730) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for p130Cas at approximately 130 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

p130Cas (protein 130 kDa Crk-associated substrate; also BCAR1) is a cytoplasmic member of the CAS family of proteins. Although its predicted MW is 93 kDa, it runs anomalously at 105-130 kDa in SDS-PAGE. It is found in a wide variety of cell types. p130Cas is involved in cell spreading and migration (but not adhesion), and its cleavage into a 31 kDa fragment promotes anoikis and cell death. Human p130Cas is 870 amino acids (aa) in length. It contains one SH3 domain (aa 3-65), a Pro‑rich region (aa 74-87), at least 10 phosphotyrosine (aa 128-410) and four phosphoserine (aa 134-639) sites, an SH3 binding motif (aa 635-643) and a HLH dimerization segment that interacts with CASL. There are multiple splice variants. There is a 22 aa substitution for aa 1-4, an alternate start site at Met30, a deletion of aa 2-211, and a four aa substitution for aa 1-4 with a deletion of aa 65-212. Over aa 66-412, human p130Cas shares 91% aa identity with mouse p130Cas.
