Enables lipid binding activity; phosphatidylinositol bisphosphate phosphatase activity; and phosphatidylinositol trisphosphate phosphatase activity. Acts upstream of or within several processes, including negative regulation of osteoclast differentiation; regulation of bone remodeling; and regulation of protein kinase B signaling. Located in Golgi apparatus. Is expressed in several structures, including brain; ear; genitourinary system; heart; and musculoskeletal system. Orthologous to human INPP4B (inositol polyphosphate-4-phosphatase type II B). [provided by Alliance of Genome Resources, Apr 2022]
