Phospho-Thr402 PAK-1,2,3 Antibody

Affinity purified rabbit polyclonal antibody

     
  • WB - Phospho-Thr402 PAK-1,2,3 Antibody AN1080
    Western blot of rat hippocampal lysate showing specific immunolabeling of the ~68k to ~70k PAK protein (Control). The phosphospecificity of this labeling is shown in the second lane (lambda-phosphatase: λ-Ptase). The blot is identical to the control except that it was incubated in λ-Ptase (1200 units for 30 min) before being exposed to the phospho-Thr402 PAK-1,2,3 antibody. The immunolabeling of PAK is completely eliminated by treatment with λ-Ptase.

Background

In mammals, there are several identified isoforms of p21-activated protein kinases or PAKs: α-PAK (also known as PAK-1) and β-PAK (also known as PAK-3) are mostly brain-specific, while -PAK (also known as PAK-2) is expressed ubiquitously (Jakobi et al., 2003). Mutations of the gene coding for PAK-3 are associated with 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).
