Product Specific Information

Antibody detects endogenous levels of PAK1/2/3 only when phosphorylated at PS144+S141+S139.

Target Information

In mammals, there are several identified isoforms of p21-Activated Protein Kinases or PAKs: alpha-PAK (also known as PAK-1) and beta-PAK (also known as PAK-3) are mostly brain-specific, while gamma-PAK (also known as PAK-2) is expressed ubiquitously (Jakobi et al., 2003). Mutations of the gene coding for PAK-3 are associated wit X-linked mental retardation and recent work indicates that PAK-3 is a key regulator of synapse formation and plasticity in the hippocampus (Boda et al., 2004). PAK-3 is thought to play a key role in regulation of cell shape and motility as well as cell death (Jakobi et al., 2003; Walter et al., 1998). Autophosphorylation of Thr402 in the protein has been found to be essential for activation of PAK (Jakobi et al., 2000).
