Name Diphosphoinositol polyphosphate phosphohydrolase 2
Synonyms
  1. DIPP-2
  2. Diadenosine 5',5'''-P1,P6-hexaphosphate hydrolase 2
  3. Nucleoside diphosphate-linked moiety X motif 4
  4. Nudix motif 4
Gene Name NUDT4
Protein Type Unknown
Biological Properties
General Function Involved in hydrolase activity
Specific Function Cleaves a beta-phosphate from the diphosphate groups in PP-InsP5 (diphosphoinositol pentakisphosphate), PP-InsP4 and [PP]2-InsP4 (bisdiphosphoinositol tetrakisphosphate), suggesting that it may play a role in signal transduction. Also able to catalyze the hydrolysis of dinucleoside oligophosphate Ap6A, but not Ap5A. The major reaction products are ADP and p4a from Ap6A. Also able to hydrolyze 5-phosphoribose 1-diphosphate.
