PAK1/PAK2/PAK3(Phospho-Thr423/Thr402/Thr421) Antibody

Description

Product Name PAK1/PAK2/PAK3(Phospho-Thr423/Thr402/Thr421) Antibody
Host Species Rabbit
Clonality Polyclonal
Purification Antibodies were produced by immunizing rabbits with synthetic phosphopeptide and KLH conjugates. Antibodies were purified by affinity-chromatography using epitope-specific phosphopeptide. Non-phospho specific antibodies were removed by chromatogramphy using non-phosphopeptide.
Applications IHC IF
Species Reactivity Hu Ms Rt
Specificity The Antibody detects endogenous level of PAK1/PAK2/PAK3 only when phosphorylated at threonine 423/402/421.
Immunogen Type Peptide-KLH
Immunogen Description Peptide sequence around phosphorylation site of threonine 423 /402/421 (R-S-T(p)-M-V) derived from Human PAK1/PAK2/PAK3.

Background

The activated kinase acts on a variety of targets. Likely to be the GTPase effector that links the Rho-related GTPases to the JNK MAP kinase pathway. Activated by CDC42 and RAC1. Involved in dissolution of stress fibers and reorganization of focal complexes. Involved in regulation of microtubule biogenesis through phosphorylation of TBCB. Activity is inhibited in cells undergoing apoptosis, potentially due to binding of CDC2L1 and CDC2L2.
