W H M R Mk Pg B Endogenous 68 Rabbit

Applications Key:  W=Western Blotting
Reactivity Key:  H=Human  M=Mouse  R=Rat  Mk=Monkey  Pg=Pig  B=Bovine
Species cross-reactivity is determined by Western blot.

Specificity / Sensitivity

Paxillin Antibody detects endogenous levels of total paxillin protein. The antibody does not cross-react with related proteins.

Source / Purification

Polyclonal antibodies are produced by immunizing rabbits with a synthetic peptide (KLH-coupled) corresponding to residues near the carboxy-terminus of human paxillin. Antibodies are purified by protein A and peptide affinity chromatography.

Western Blotting

Western Blotting

Western blot analysis of extracts from various cell lines, using Paxillin Antibody.

Background

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).
