Anti-phospho-PAK1 (Ser199/Ser204) Antibody

p21-activated kinases (PAK) are Ser/Thr kinases, which are activated by, and are effectors of Rho family of GTPases. As such, they are implicated in Actin polymerization and activation of the stress-activated kinase cascades. PAK1 is phosphorylated by cdk5, resulting in its inhibition. PAK2 can be activated by Caspase-cleavage in addition to p21-binding, implicating it in cytoskeletal changes during apoptosis. PAK3 is expressed at high levels in post-mitotic neurons of the developing post-natal cerebral cortex and hippocampus, and is the mutant gene thought responsible for non-syndromic X-linked mental retardation.

Recognizes PAK1 phosphorylated on Ser199 and Ser204 (human)/Ser198 and Ser203 (mouse). Immunogen sequence is higly homolgous (greater than 90%) with PAK2 and PAK3.

Amino Acids encompassing and including phosphorylated Ser199 and Ser204 of human PAK1. Sequence is highly homologous (greater than 90%) to PAK2 and PAK3.
