| General description: | p21-activated kinases are a family of highly conserved serine/threonine protein kinases that are activated by small GTPases of Cdc42 and Rac families. There are 2 groups of PAKs in mammals, group A and B. The group A members are three isoforms, PAK1, PAK2, and PAK3 (also known as α-PAK, γ-PAK, and β-PAK, respectively). PAKs are actively involved in regulation of MAPK pathways by phosphorylation of Raf-1 and MEK-1. They also regulate cytoskeletal reorganization by interaction with GTPases. Autophosphorylation of serine 141 (serine 144 for PAK1 and serine 139 for PAK3), catalyzed by Cdc42, is required for activation of PAK. The antibody detects human PAK1 (46% homologous), PAK2, and PAK3 (46% homologous). Other species have not been tested. |
| Immunogen: | synthetic phosphopeptide derived from the region of human PAK2 that contains serine 141. |
