Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting, IF-IC=Immunofluorescence (Immunocytochemistry),


Species predicted to react based on 100% sequence homology: Zebrafish,

Specificity / Sensitivity

Phospho-Paxillin (Tyr118) Antibody detects endogenous levels of paxillin only when phosphorylated at tyrosine 118. The antibody does not cross-react with other tyrosine phosphorylated proteins.

Phospho-Paxillin (Tyr118)抗体仅能识别在118位酪氨酸磷酸化后的内源性paxillin蛋白。抗体与其他酪氨酸磷酸化的蛋白没有交叉反应。

Source / Purification

Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Tyr118 of human paxillin. Antibodies are purified by protein A and peptide affinity chromatography.

Paxillin is a multi-domain protein that localizes primarily to focal adhesion sites to the extracellular matrix (1). Paxillin is one of the key components of integrin signaling and tyrosine phosphorylation of paxillin is required for integrin-mediated cytoskeletal reorganization (2). Paxillin is phosphorylated by another focal adhesion component, focal adhesion kinase (FAK), at Tyr118 (3,4). Phospho-Tyr118 may provide a docking site for recruitment of other signaling molecules to focal adhesions. It has been shown that the SH2 domain of Crk binds to the phosphorylated Tyr118 of paxillin (5).
