Predicted to enable inositol-1,4,5-trisphosphate 5-phosphatase activity and phosphatidylinositol-4,5-bisphosphate 5-phosphatase activity. Predicted to be involved in inositol phosphate dephosphorylation and phosphatidylinositol dephosphorylation. Predicted to act upstream of or within several processes, including flagellated sperm motility; regulation of protein processing; and spermatogenesis. Predicted to be integral component of membrane. Predicted to be active in cytosol and membrane. Orthologous to human INPP5B (inositol polyphosphate-5-phosphatase B). [provided by Alliance of Genome Resources, Apr 2022]
