Previous Symbols for NMRK1 Gene
Nicotinamide adenine dinucleotide (NAD+) is essential for life in all organisms, both as a coenzyme for oxidoreductases and as a source of ADP-ribosyl groups used in various reactions. Nicotinic acid and nicotinamide, collectively known as niacin, are the vitamin precursors of NAD+. Nicotinamide riboside kinases, such as NRK1, function to synthesize NAD+ through nicotinamide mononucleotide using nicotinamide riboside as the precursor (Bieganowski and Brenner, 2004 [PubMed 15137942]).[supplied by OMIM, Mar 2008]
GeneCards Summary for NMRK1 Gene
NMRK1 (Nicotinamide Riboside Kinase 1) is a Protein Coding gene. Among its related pathways are Nicotinate and nicotinamide metabolism and Nicotinate and nicotinamide metabolism. GO annotations related to this gene include uridine kinase activity and ribosylnicotinamide kinase activity. An important paralog of this gene is NMRK2.
UniProtKB/Swiss-Prot for NMRK1 Gene
Catalyzes the phosphorylation of nicotinamide riboside (NR) and nicotinic acid riboside (NaR) to form nicotinamide mononucleotide (NMN) and nicotinic acid mononucleotide (NaMN). The enzyme also phosphorylates the antitumor drugs tiazofurin and 3-deazaguanosine.
