Our Anti-PAK-1,2,3 (Thr402) rabbit polyclonal phosphospecific primary antibody from PhosphoSolutions is produced in-house. It detects mouse and rat PAK-1,2,3 (Thr402) and is antigen affinity purified from pooled serum. It is great for use in WB.
Western blot of rat hippocampal lysate showing specific immunolabeling of the ~68 kDa to ~70 kDa PAK protein phosphorylated at Ser402 in the first lane (-). Phosphospecificity is shown in the second lane (+) where the immunolabeling is completely eliminated by blot treatment with lambda phosphatase (λ-Ptase, 1200 units for 30 minutes).
Anti-PAK-1,2,3 (Thr402) Antibody
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 γ-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 Thr-402 in the protein has been found to be essential for activation of PAK (Jakobi et al., 2000).
Antigen Affinity Purified from Pooled Serum
Synthetic phospho-peptide corresponding to amino acid residues surrounding Thr402 of rat p21 activated kinase 2 (PAK-2), conjugated to keyhole limpet hemocyanin (KLH). The peptide sequence used is identical in PAK-1, 2 and 3. Note: Thr402 in PAK-2 corresponds to Thr423 in human PAK-1.
