General annotation (Comments)

Function	Inositol 5-phosphatase, which converts inositol 1,4,5-trisphosphate to inositol 1,4-bisphosphate. Also converts phosphatidylinositol 4,5-bisphosphate to phosphatidylinositol 4-phosphate and inositol 1,3,4,5-tetrakisphosphate to inositol 1,3,4-trisphosphate in vitro. May be involved in modulation of the function of inositol and phosphatidylinositol polyphosphate-binding proteins that are present at membranes ruffles By similarity.
Catalytic activity	D-myo-inositol 1,4,5-trisphosphate + H2O = myo-inositol 1,4-bisphosphate + phosphate. 1D-myo-inositol 1,3,4,5-tetrakisphosphate + H2O = 1D-myo-inositol 1,3,4-trisphosphate + phosphate.
Subcellular location	Cytoplasm By similarity. Note: Predominantly localized to membrane ruffles By similarity.
Domain	The 5 Arg-Ser-Xaa-Ser-Xaa-Xaa (RSXSXX) motifs may constitute binding sites for the 14-3-3 protein.
Post-translational modification	Phosphorylated at Ser/Thr residues By similarity.
Sequence similarities	Belongs to the inositol-1,4,5-trisphosphate 5-phosphatase type II family.
Sequence caution	The sequence AAD15618.1 differs from that shown. Reason: Erroneous gene model prediction.
