Anti-NMRK2 antibodies are used in the immunodetection of the protein nicotinamide riboside kinase 2. In humans, the canonical protein has a reported length of 230 amino acid residues and a mass of 26 kDa. Up to 2 different isoforms have been reported for this protein. It is reported to be highly expressed in the skeletal muscle and, at a much lower level, in the heart. A member of the Uridine kinase protein family, NMRK2 is known to catalyze the phosphorylation of nicotinamide riboside (NR) and nicotinic acid riboside (NaR) to form nicotinamide mononucleotide (NMN) and nicotinic acid mononucleotide (NaMN). Synonyms for this target antigen include MIBP, NRK2, NRK 2, RNK 2, integrin beta-1-binding protein 3, and ITGB1BP3. NMRK2 gene orthologs have been reported in the mouse, rat, bovine, chimpanzee and chicken species. Some NMRK2 antibodies may have been used in research and have associated citations. These antibodies are most commonly used in Western Blot experiments, among other applications.
