    Summary
    Predicted to enable phosphatidylinositol-4,5-bisphosphate 4-phosphatase activity. Involved in positive regulation of TORC1 signaling and proton-transporting V-type ATPase complex assembly. Located in bounding membrane of organelle and plasma membrane. Orthologous to human PIP4P1 (phosphatidylinositol-4,5-bisphosphate 4-phosphatase 1).

    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.
