PAK2 Antibody

PAK2 Antibody: The p21-activated kinases (PAKs) are serine-threonine kinases that bind to the active forms of Cdc42 and Rac. They are divided into two groups, the first of which include PAK1, 2 and 3, and can be activated by Cdc42/Rac binding. Group 1 PAKs contain an autoinhibitory domain whose activity is regulated by Cdc42/Rac binding. The group 1 PAKs are known to be involved in cellular processes such as gene transcription, apoptosis, and cell morphology and motility. Much less is known about the second group, which includes PAK4, 5 and 6, and are not activated by Cdc42/Rac binding. Of the six PAK proteins, only PAK2 is ubiquitously expressed and cleaved by caspase-3. This cleavage removes the amino-terminal regulatory domain and generates a constitutively active kinase fragment. Recent experiments have shown that following cleavage, the active fragment is myristoylated and directed to the plasma membrane and membrane ruffles where it promotes cell death via increased signaling through the c-Jun N-terminal kinase pathway, but without compromising mitochondrial integrity.

Independent Antibody Validation in Cell lines (Figure 2) shows similar PAK2 expression profile in human, mouse and rat cell lines detected by two independent anti-PAK2 antibodies that recognize different epitopes, 3885 against C-terminus domain and 3887 against N-terminus domain. PAK2 proteins are detected in the most tested cell lines at different expression levels by the two independent antibodies. Independent Antibody Validation in Cell lines3885 3887

PAK2 antibody can be stored at 4˚ C for three months and -20˚ C, stable for up to one year. As with all antibodies care should be taken to avoid repeated freeze thaw cycles. Antibodies should not be exposed to prolonged high temperatures.

Human PAK2 has only one isoform (524aa, 58kD) . Mouse PAK2 has one isoform (524aa, 58kD) and rat PAK2 also has one isoform (524aa, 58kD) . 3887 can detect the isoforms of human, mouse and rat.
