  • Function

    The PI(3,5)P2 regulatory complex regulates both the synthesis and turnover of phosphatidylinositol-3,5-bisphosphate (PtdIns(3,5)P2). Acts as a positive activator of PIKfyve kinase activity. Also required to maintain normal levels of phosphatidylinositol 3-phosphate (PtdIns(3)P) and phosphatidylinositol 5-phosphate (PtdIns(5)P). Plays a role in the biogenesis of endosome carrier vesicles (ECV) / multivesicular bodies (MVB) transport intermediates from early endosomes.
  • Tissue specificity

    Ubiquitously expressed.
  • Sequence similarities

    Belongs to the VAC14 family.
    Contains 6 HEAT repeats.
  • Domain

    The C-terminal domain (residues 523-782) mediates homomeric interactions and is necessary for the formation and maintenance of the PI(3,5)P2 regulatory complex.
  • Cellular localization

    Endosome membrane. Microsome membrane. Mainly associated with membranes of the late endocytic pathway.
