PKM2 is a protein encoded by the PKM gene which is approximately 57, 9 kDa. PKM2 is localised to the cytoplasm and nucleus. It is involved in glucose metabolism, innate immune system and carbon metabolism and glucose/energy metabolism. It is a glycolytic enzyme that catalyzes the transfer of a phosphoryl group from phosphoenolpyruvate to ADP, generating ATP. It stimulates POU5F1-mediated transcriptional activation and pays a general role in caspase independent cell death of tumor cells. PKM2 is specifically expressed in proliferating cells, such as embryonic stem cells, embryonic carcinoma cells, as well as cancer cells. Mutations in the PKM gene may result in pyruvate kinase deficiency and gastric diffuse adenocarcinoma. STJ95142 was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen. This polyclonal antibody binds to endogenous levels of PKM2 protein.
