| Multiple Inositol Polyphosphate Phosphatase from Nogimori et al, JBC 266(25); 1991: 16499-506 MIPP clustered in ER. Distinct transporters present for cytosolic substrates. Accounts for 30-45% of total 3-phosphatase activity against substrates, hence cytosolic counterparts of this enzyme must be present (as per Chi et al, MCB 20; 2000: 6496-507) |
