Background:
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.
Sequence: Phospho-Paxillin (Ser-178) synthetic peptide corresponds to amino acid residues around serine 178 of human paxillin. This human sequence is highly conserved in rat and mouse paxillin.
Specificity: The peptide is specifically recognized by anti-Paxillin (Ser-178) phospho-specific antibody (PP1051) in ELISA, and has been shown to block the reactivity of PP1051 during Western blot. In addition, the peptide is recommended for use in blocking PP1051 reactivity in immunocytochemistry.
Buffer/Storage:
Blocking Peptide is supplied in 50µl phosphate-buffered saline and 0.05% sodium azide. Store at –20°C. Stable for 1 year.
