Summary: Enables inositol bisphosphate phosphatase activity; phosphatidylinositol-3,4,5-trisphosphate 5-phosphatase activity; and vasopressin receptor activity. Involved in several processes, including negative regulation of phosphate metabolic process; negative regulation of signal transduction; and regulation of cellular macromolecule biosynthetic process. Acts upstream of or within glucose homeostasis; in utero embryonic development; and response to insulin. Located in endoplasmic reticulum. Human ortholog(s) of this gene implicated in congenital muscular dystrophy with cataracts and intellectual disability. Orthologous to human INPP5K (inositol polyphosphate-5-phosphatase K).

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.
