    Summary
    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 phosphatidylinositol 3-kinase/protein kinase B signal transduction. Predicted to be active in cytoplasm. 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, Dec 2024]

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
