General annotation (Comments)

Function	The PI(3,5)P2 regulatory complex regulates both the synthesis and turnover of phosphatidylinositol-3,5-bisphosphate (PtdIns(3,5)P2). Major enzyme required for hyperosmotic shock-induced turnover of PtdIns(3,5)P2 and requires VAC14 for this function. In vivo, mediates turnover of PtdIns(3,5)P2 at the vacuole membrane necessary for vacuolar size control. In vitro, catalyzes the removal of phosphate from the fifth hydroxyl of the myo-inositol ring of phosphatidylinositol-3,5-bisphosphate. Ref.1 Ref.4 Ref.6 Ref.8
Catalytic activity	1-phosphatidyl-1D-myo-inositol 3,5-bisphosphate + H2O = 1-phosphatidyl-1D-myo-inositol 3-phosphate + phosphate. Ref.4
Cofactor	Magnesium. Ref.4
Subunit structure	Component of the PI(3,5)P2 regulatory complex, composed of ATG18, FIG4, FAB1, VAC14 and VAC7. VAC14 nucleates the assembly of the complex and serves as a scaffold.
Subcellular location	Vacuole membrane; Peripheral membrane protein. Note: Localized to the limiting membrane of the vacuole. Localization requires VAC14 and FAB1. Ref.1 Ref.4 Ref.8 Ref.9
Miscellaneous	Present with 339 molecules/cell in log phase SD medium. Ref.5
Sequence similarities	Contains 1 SAC domain.
