Immunogen C-terminal peptide (last 15 amino acids) of human Csk binding protein coupled to KLH.
Clone PAG-C1
Isotype IgG2b
Specificity The antibody PAG-C1 recognizes an epitope located in the C-terminal domain ofCsk-binding protein (Cbp / PAG), a 46 kDa ubiquitously expressed transmembrane adaptorprotein present in membrane rafts (glycosphingolipid-enriched microdomains), whichhowever migrates on SDS PAGE gels anomalously as an 80 kDa molecule.
Purification Purified from ascites by protein-A affinity chromatography.
Purity > 95% (by SDS-PAGE)
Alternative Name PAG1
Background PAG (phosphoprotein associated with GEMs), also known as Cbp (Csk-binding protein), is aubiquitously expressed 46 kDa transmembrane adaptor protein present in membrane rafts(glycosphingolipid-enriched microdomains), which however migrates on SDS PAGE gelsanomalously as an 80 kDa molecule. Following tyrosine phosphorylation by Src familykinases, PAG binds and thereby activates the protein tyrosine kinase Csk, the majornegative regulator of the Src family kinases. Signaling via the B-cell receptor in B cells orhigh affinity IgE receptor (FcepsilonRI) in mast cells leads to PAG increased tyrosinephosphorylation and Csk binding, while T cell receptor signaling causes PAGdephosphorylation, loss of Csk binding and increased activation of the protein tyrosinekinase Lck.
