Anti-PKM2 (isoform M2) antibody produced in rabbit

NA.44

Pyruvate Kinase (PK) has four known isoforms, namely, L, R, M1 and M2. PK isoform M1 is expressed during the development of the embryo and is the dominant isoform in cardiac, brain and skeletal muscle tissues. The M2 isoform has been linked to cancer metastasis .

Anti-PKM2 (isoform M2) antibody is specific for human PKM2 (isoform M2). The product is expected to react with rat and mouse PKM2. In immunoblotting, detection of the PKM2 (isoform M2) band is specifically inhibited by the PKM2 (isoform M2) immunizing peptide.

Anti-PKM2 (isoform M2) antibody produced in rabbit has been used in:

• chromatin immunoprecipitation (chip) assay
• western blotting
• immunofluorescence
• immunohistochemistry

Pyruvate Kinase (PK) is a key regulatory enzyme in glycolysis. Tumor cells have been reported to exclusively overexpress the embryonic M2 isoform. The tumor metabolome is characterized by high glycolytic turnover rate and tumor cells are able to proliferate under conditions of aerobic glycolysis, known as the Warburg effect. Knockdown of the M2 isoform in human cancer cell lines and its replacement by the M1 isoform has been shown to lead to reversal of the Warburg effect, and reduced ability to form tumors in mouse xenografts. Phosphorylation of the M2 isoform at Tyr105 inhibits its activity and is common in human cancers, suggesting that Tyr105 is a critical metabolic switch in cancer cells that promotes tumorigenesis.
