Catalysis of the reaction: inositol-1,3,4,5-tetrakisphosphate + H2O = inositol-1,4,5-trisphosphate + phosphate. Catalysis of the reaction: phosphatidylinositol-4-phosphate + H2O = phosphatidylinositol + orthophosphate. Catalysis of the removal of one of the three phosphate groups of an inositol trisphosphate. Catalysis of the removal the of the 4-phosphate group of a phosphatidylinositol phosphate. Catalysis of the removal the of the 5-phosphate group of a phosphatidylinositol phosphate. Catalysis of the removal of one of the three phosphate groups of a phosphatidylinositol trisphosphate. Catalysis of the removal of one of the two phosphate groups of a phosphatidylinositol bisphosphate. Catalysis of the hydrolysis of phosphoric monoesters, releasing inorganic phosphate. Catalysis of the reaction: RPO-R' + H2O = RPOOH + R'H. This reaction is the hydrolysis of any phosphoric ester bond, any ester formed from orthophosphoric acid, O=P(OH)3. Catalysis of the reaction: 1-phosphatidyl-1D-myo-inositol 3-phosphate + H2O = 1-phosphatidyl-1D-myo-inositol + phosphate. Catalysis of the reaction: inositol-1,3,4,5,6-pentakisphosphate + H2O = inositol-1,4,5,6-tetrakisphosphate + phosphate. Catalysis of the reaction: inositol-1,4,5,6-tetrakisphosphate + H2O = inositol-1,4,5-trisphosphate + phosphate. Catalysis of the removal of one of the two phosphate groups of an inositol bisphosphate. Catalysis of the removal of a phosphate group from phosphorylated myo-inositol (1,2,3,5/4,6-cyclohexanehexol) or a phosphatidylinositol. Catalysis of the reaction: myo-inositol hexakisphosphate + H2O = myo-inositol pentakisphosphate (mixed isomers) + phosphate. Catalysis of the reaction: myo-inositol 1-phosphate + H2O = myo-inositol + phosphate.
