Rabbit Anti-Paxillin, phosphorylated, Tyr31 (PXN)
Paxillin is a 68kD cytoskeletal adapter protein involved in organization and function of focal adhesions, which are critical to cell adhesion and migration. This in turn plays a role in a wide variety of processes including embryogenesis, organogenesis, wound repair, inflammation and cancer. Paxillin contains LD motifs, LIM domains, SH3 and SH2 binding domains that serve as docking sites for cytoskeletal proteins, tyrosine kinases (e.g., FAK, Pyk2, Src), serine/threonine kinases, GTPase activating proteins and other adaptor proteins (e.g., actin, vinculin, Crk). Tyrosine 31, a Crk binding site of paxillin, is phosphorylated during integrin-mediated cell adhesion.
