PAK1 is a member of the p21-activated kinases (PAKs) which have been implicated in the regulation of cell morphology, motility and transformation. These serine/threonine kinases are activated by and are effectors of small GTPases, CDC42 and RAC. PAK1 belongs to the Group I PAKs which also includes PAK2 and PAK3 (1). PAK1 is a key regulator of the actin cytoskeleton, adhesion and cell motility. Inactive dimeric PAK1 is mainly cytosolic and interaction with the activators Cdc42-GTP and Rac1-GTP stimulates the kinase at the sites of cellular protrusions forming adhesions to the extracellular matrix (2).

Recognizes the PAK1 protein
Western blot PAK1 from human and mouse cells
PAK1 from other species may also be detectable
Synthetic peptide corresponding to amino acids 210-214 of human PAK1
Store at 4°C (add 0.1% NaN3) for several months, and at -20°C for longer periods. For optimal storage, aliquot target into smaller quantities after centrifugation and store at recommended temperature. For most favorable performance, avoid repeated handling and multiple freeze/thaw cycles.
Representative western blot with Anti-PAK1 (1:1000) using 3 μg, 10 μg, and 30 μg of Jurkat cel lysate.
Representative western blot with Anti-PAK1 (1:1000) using 20 ng of human recombinant PAK1, PAK2, PAK3, PAK4, and PAK7.
