DE   phosphatidylinositol-3,4-bisphosphate 4-phosphatase.
AN   D-myo-inositol-3,4-bisphosphate 4-phosphohydrolase.
AN   inositol-3,4-bisphosphate 4-phosphatase.
AN   inositol polyphosphate 4-phosphatase.
AN   inositol polyphosphate 4-phosphatase type II.
AN   phosphoinositide 4-phosphatase.
CA   a 1,2-diacyl-sn-glycero-3-phospho-(1D-myo-inositol-3,4-bisphosphate) +
CA   H2O = a 1,2-diacyl-sn-glycero-3-phospho-(1D-myo-inositol-3-phosphate) +
CA   phosphate.
CC   -!- Magnesium-independent.
CC   -!- This enzyme still works when the 2,3-bis(acyloxy)propyl group is
CC       removed, i.e., it hydrolyzes Ins(1,3,4)P3 to Ins(1,3)P2.
CC   -!- It also converts Ins(3,4)P2 into Ins-3-P.
