Summary: Enables inositol monophosphate 4-phosphatase activity and phosphatidylinositol phosphate 4-phosphatase activity. Involved in several processes, including negative regulation of axon regeneration; phosphatidylinositol dephosphorylation; and positive regulation of receptor recycling. Acts upstream of or within cardiac muscle hypertrophy in response to stress; phosphatidylinositol 3-kinase/protein kinase B signal transduction; and phosphatidylinositol catabolic process. Located in several cellular components, including cytoplasmic vesicle; dendrite; and neuronal cell body. Is expressed in several structures, including brain; genitourinary system; heart; retina; and spleen. Orthologous to human INPP5F (inositol polyphosphate-5-phosphatase F).

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.
