Anti-PAK2 antibodies are used in the immunodetection of the protein p21 (RAC1) activated kinase 2. In humans, the canonical protein has a reported length of 524 amino acid residues and a mass of 58 kDa. Its subcellular localization is in the nucleus and cytoplasm. It is ubiquitously expressed across many tissue types. A member of the STE Ser/Thr protein kinase protein family, PAK2 is a serine/threonine protein kinase that plays a role in a variety of different signaling pathways including cytoskeleton regulation, cell motility, cell cycle progression, apoptosis or proliferation. Synonyms for this target antigen include PAK65, PAKgamma, serine/threonine-protein kinase PAK 2, S6/H4 kinase, gamma-PAK, and KNO2. PAK2 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. Over 540 citations in the literature describe the use of PAK2 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
