About NAPRT

Cytogenetic location: 8q24.3 Genomic coordinates (GRCh38): 8:143,572,874-143,578,330 (from NCBI)

This gene has 14 transcripts (splice variants), 1 gene allele, 188 orthologues and 1 paralogue. Ubiquitous expression in duodenum (RPKM 19.1), small intestine (RPKM 16.7) and 25 other tissues.

Summary

Nicotinic acid (NA; niacin) is converted by nicotinic acid phosphoribosyltransferase (NAPRT; EC 2.4.2.11) to NA mononucleotide (NaMN), which is then converted to NA adenine dinucleotide (NaAD), and finally to nicotinamide adenine dinucleotide (NAD), which serves as a coenzyme in cellular redox reactions and is an essential component of a variety of processes in cellular metabolism including response to stress (Hara et al., 2007).[supplied by OMIM, Mar 2008]
