Anti-NMRK1 antibodies are used in the immunodetection of the protein nicotinamide riboside kinase 1. In humans, the canonical protein has a reported length of 199 amino acid residues and a mass of 23.2 kDa. Up to 2 different isoforms have been reported for this protein. It is notably widely expressed in many tissue types. A member of the Uridine kinase protein family, NMRK1 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 NRK1, bA235O14.2, NRK 1, RNK 1, nicotinic acid riboside kinase 1, and C9orf95. NMRK1 gene orthologs have been reported in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of NMRK1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunofluorescence are also common applications.
