MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes a protein that catalyzes the condensation of nicotinamide with 5-phosphoribosyl-1-pyrophosphate to yield nicotinamide mononucleotide, one step in the biosynthesis of nicotinamide adenine dinucleotide. The protein belongs to the nicotinic acid phosphoribosyltransferase (NAPRTase) family and is thought to be involved in many important biological processes, including metabolism, stress response and aging. This gene has a pseudogene on chromosome 10. [provided by RefSeq, Feb 2011]
PHENOTYPE: Mice homozygous for a null allele exhibit embryonic lethality prior to E10.5. Mice heterozygous for a null allele exhibit increased fasted glucose in male mice and impaired glucose tolerance and decresed glucose-stimulated insulin secretion in female mice. [provided by MGI curators]
