| + | == Function == | ||
| + | [https://www.uniprot.org/uniprot/NUD12_MOUSE NUD12_MOUSE] Hydrolyzes NAD(P)H to NMNH and AMP (2',5'-ADP), and diadenosine diphosphate to AMP. Has also activity towards NAD(P)(+), ADP-ribose and diadenosine triphosphate. May act to regulate the concentration of peroxisomal nicotinamide nucleotide cofactors required for oxidative metabolism in this organelle (By similarity). | ||

| + | == Publication Abstract from PubMed == | ||
| + | We recently demonstrated that mammalian cells harbor nicotinamide adenine dinucleotide (NAD)-capped messenger RNAs that are hydrolyzed by the DXO deNADding enzyme. Here, we report that the Nudix protein Nudt12 is a second mammalian deNADding enzyme structurally and mechanistically distinct from DXO and targeting different RNAs. The crystal structure of mouse Nudt12 in complex with the deNADding product AMP and three Mg(2+) ions at 1.6 A resolution provides insights into the molecular basis of the deNADding activity in the NAD pyrophosphate. Disruption of the Nudt12 gene stabilizes transfected NAD-capped RNA in cells, and its endogenous NAD-capped mRNA targets are enriched in those encoding proteins involved in cellular energetics. Furthermore, exposure of cells to nutrient or environmental stress manifests changes in NAD-capped RNA levels that are selectively responsive to Nudt12 or DXO, respectively, indicating an association of deNADding to cellular metabolism. | ||
