CST, 3291S, Phospho-Pyk2 (Tyr402) Antibody

Polyclonal Antibody for studying Pyk2 (Tyr402) phosphate. Validated for Western Blotting,Immunoprecipitation. Highly specific and rigorously validated in-house, Phospho-Pyk2 (Tyr402) Antibody (CST #3291) is ready to ship. Product Usage Information Western Blotting: 1:1000 Immunoprecipitation: 1:100 Storage Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at -20°C. Do not aliquot the antibody. Protocol Available protocols: Western Blotting, Immunoprecipitation Specificity / Sensitivity Phospho-Pyk2 (Tyr402) Antibody detects endogenous levels of Pyk2 only when phosphorylated at tyrosine 402. This antibody may cross-react with other phospho-tyrosine containing proteins. Species Reactivity: Human, Mouse Source / Purification Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Tyr402 of human Pyk2. Antibodies are purified by protein A and peptide affinity chromatography. Background Protein-tyrosine kinase 2 (Pyk2), also called CAKβ, RAFTK, and CADTK, is a nonreceptor tyrosine kinase structurally related to focal adhesion kinase (FAK) (1-4). Pyk2 is predominantly expressed in cells derived from hematopoietic lineages and in the central nervous system. Pyk2 is one of the signaling mediators for the G protein-coupled receptors and MAP kinase signaling pathway. It plays an important role in cell spreading and migration (5-7). Pyk2 is tyrosine phosphorylated and activated upon ligation of TCR (8,9). Phosphorylated Tyr402 of Pyk2 is required for the phosphorylation of other tyrosines on Pyk2 and provides a binding site for Fyn SH2 in the T-cell activation (10).
