PKM Antibody – Goat Polyclonal

This gene encodes a protein involved in glycolysis. The encoded protein is a pyruvate kinase that catalyzes the transfer of a phosphoryl group from phosphoenolpyruvate to ADP, generating ATP and pyruvate. This protein has been shown to interact with thyroid hormone and may mediate cellular metabolic effects induced by thyroid hormones. This protein has been found to bind Opa protein, a bacterial outer membrane protein involved in gonococcal adherence to and invasion of human cells, suggesting a role of this protein in bacterial pathogenesis. Several alternatively spliced transcript variants encoding a few distinct isoforms have been reported. [provided by RefSeq, May 2011]

PKM2: one of three rate-limiting enzymes in glycolysis. It catalyzes the transfer of a phosphate group from phosphoenolpyruvate (PEP) to ADP, yielding one molecule ATP and a pyruvate molecule, which is a central metabolic intermediate that can be used as a building block or oxidized further. Overexpressed in a variety of cancers. Interacts with thyroid hormone, and thus may mediate cellular metabolic effects induced by thyroid hormones. Binds Opa protein, a bacterial outer membrane protein involved in gonococcal adherence to and invasion of human cells, suggesting a role of this protein in bacterial pathogens is. There are several mammalian isozymes of pyruvate kinase encoded by different genes. The L type predominates in liver, and the M type in muscle and brain. Two alternatively spliced human isoforms of PKM2 have been reported.
