Diphosphoinositol polyphosphate phosphohydrolases (DIPP), also known as nucleoside diphosphate-linked moiety X motif (NUDT) proteins, dephosphorylate inositol bisdiphospho-tetrakisphosphate ((PP)2-IP4) to inositol 5-diphospho-1,2,3,4,6-pentakisphosphate (5-PP-IP5). The NUDT proteins involved are: nucleoside diphosphate-linked moiety X motif 3 (NUDT3), 4 (NUDT4), 10 (NUDT10), and 11 (NUDT11). The reactants consumed are: inositol 1,5-bisdiphospho-2,3,4,6-tetrakisphosphate (1,5-(PP)2-IP4) and inositol 3,5-bisdiphospho-1,2,4,6-tetrakisphosphate (3,5-(PP)2-IP4).

The following lists the above proteins with their corresponding literature references: NUDT3 (Safrany et al. 1999, Safrany et al. 1998, Yang et al. 1999, Caffrey et al. 2000), NUDT4 (Caffrey et al. 2000), NUDT10 (Leslie et al. 2002, Hidaka et al. 2002) and NUDT11 (Leslie et al. 2002, Hidaka et al. 2002).
