Diphosphoinositol polyphosphate phosphohydrolase 2, also known as nucleoside diphosphate-linked moiety X motif 4 (NUDT4), dephosphorylates diphospho- tetrakisphosphate (PP-IP4) to inositol 1,3,4,5,6-pentakisphosphate (I(1,3,4,5,6)P5). The products made are: inositol 5-diphospho-1,3,4,6-tetrakisphosphate (5-PP-IP4); inositol 1-diphospho-3,4,5,6-tetrakisphosphate (1-PP-IP4); and inositol 3-diphospho-1,4,5,6-tetrakisphosphate (3-PP-IP4).

The following lists the above protein with its corresponding literature references: NUDT4 (Saiardi et al. 2001, Saiardi et al. 2000).
