Anti-p130cas (Breast Cancer Anti-estrogen Resistance Protein 1, CRK-associated Substrate, Cas Scaffo

p130Cas is a cytoplasmic member of the CAS family of proteins. Although its predicted MW is 93kD, it runs anomalously at 105-130kD 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 31kD fragment promotes anoikis and cell death. Human p130Cas is 870aa in length. It contains one SH3 domain aa3-65, a Pro-rich region aa74-87, at least 10 phosphotyrosine aa128-410 and four phosphoserine aa34-639 sites, an SH3 binding motif aa635-643 and a HLH dimerization segment that interacts with CASL. There are multiple splice variants. There is a 22aa substitution for aa1-4, an alternate start site at Met30, a deletion of aa2-211, and a four aa substitution for aa1-4 with a deletion of aa65-212. Over aa66-412, human p130Cas shares 91% aa identity with mouse p130Cas. Applications: Suitable for use in Western Blot. Other applications not tested.
