Automated description from the Alliance of Genome Resources (Release 5.2.2)
Enables inositol-1,4,5-trisphosphate 5-phosphatase activity and phosphatidylinositol-4,5-bisphosphate 5-phosphatase activity. Involved in phosphatidylinositol dephosphorylation. Acts upstream of or within several processes, including flagellated sperm motility; regulation of protein processing; and spermatogenesis. Located in cytosol. Is integral component of membrane. Is expressed in several structures, including alimentary system; genitourinary system; liver; lung; and spleen. Orthologous to human INPP5B (inositol polyphosphate-5-phosphatase B).
