MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] BPNT1, also called bisphosphate 3-prime-nucleotidase, or BPntase, is a member of a magnesium-dependent phosphomonoesterase family. Lithium, a major drug used to treat manic depression, acts as an uncompetitive inhibitor of BPntase. The predicted human protein is 92% identical to mouse BPntase. BPntase's physiologic role in nucleotide metabolism may be regulated by inositol signaling pathways. The inhibition of human BPntase may account for lithium-induced nephrotoxicity.

PHENOTYPE: Mice homozygous for a knock-out allele develop severe liver pathologies, including hypoproteinemia, abnormal hepatocellular morphology and damage, and in severe cases, whole body edema and premature death. [provided by MGI curators]
