Previous GeneCards Identifiers for NUDT3 Gene
NUDT3 belongs to the MutT, or Nudix, protein family. Nudix proteins act as homeostatic checkpoints at important stages in nucleoside phosphate metabolic pathways, guarding against elevated levels of potentially dangerous intermediates, like 8-oxo-dGTP, which promotes AT-to-CG transversions (Safrany et al., 1998 [PubMed 9822604]).[supplied by OMIM, Feb 2011]
GeneCards Summary for NUDT3 Gene
NUDT3 (Nudix Hydrolase 3) is a Protein Coding gene. Among its related pathways are Metabolism and Inositol phosphate metabolism. Gene Ontology (GO) annotations related to this gene include hydrolase activity and diphosphoinositol-polyphosphate diphosphatase activity. An important paralog of this gene is NUDT4.
UniProtKB/Swiss-Prot Summary for NUDT3 Gene
Cleaves a beta-phosphate from the diphosphate groups in PP-InsP5 (diphosphoinositol pentakisphosphate) and [PP]2-InsP4 (bisdiphosphoinositol tetrakisphosphate), suggesting that it may play a role in signal transduction. InsP6 (inositol hexakisphosphate) is not a substrate. Acts as a negative regulator of the ERK1/2 pathway. Also able to catalyze the hydrolysis of dinucleoside oligophosphates, with Ap6A and Ap5A being the preferred substrates. The major reaction products are ADP and p4a from Ap6A and ADP and ATP from Ap5A. Also able to hydrolyze 5-phosphoribose 1-diphosphate.
