Paxillin, a focal adhesion protein, is involved in focal adhesion formation during cell adhesion and migration. Paxillin contains LD motifs, LIM domains, and SH3-/SH2-binding domains that participate in a variety of protein-protein interactions with kinases, GTPase-activating proteins, and cytoskeletal proteins. Phosphorylation of paxillin occurs at both tyrosine and serine sites. Serine phosphorylation of paxillin occurs in response to growth-factor activation and fibronectins. Both JNK1 and cdc2 kinases can phosphorylate serine 178 in paxillin. The mutant form of paxillin (S178A) decreases the migration of keratocytes and epithelial cells. Thus, phosphorylation paxillin at serine 178 may be important during cell migration.

Western blot analysis of A431 cells. The blot was probed with rabbit polyclonal anti-Paxillin (PP1161) at 1:500 & 1:2000 (lanes 1 & 2) or with mouse monoclonal anti-Paxillin (PM1071) at 1:2000 & 1:5000 (lanes 3 & 4).

A synthetic peptide (coupled to KLH) corresponding to amino acid residues in the C-terminal region of human Paxillin. This peptide sequence is highly conserved in rat and mouse paxillins, and is found in all three paxillin isoforms (α, β,and γ).
