What is the function of this protein?
The PI(3,5)P2 regulatory complex regulates both the synthesis and turnover of phosphatidylinositol 3,5-bisphosphate (PtdIns(3,5)P2).  Catalyzes the phosphorylation of phosphatidylinositol 3-phosphate on the fifth hydroxyl of the myo-inositol ring, to form phosphatidylinositol 3,5-bisphosphate (PubMed:16492811, PubMed:9811604).  Required for endocytic-vacuolar pathway and nuclear migration (PubMed:9751732, PubMed:16492811, PubMed:9811604).  The product of the reaction, PI(3,5)P2 is an important regulator of vacuole homeostasis perhaps by controlling membrane flux to and/or from the vacuole (PubMed:9811604, PubMed:9763421).  PI(3,5)P2 regulates the transition between trans-SNARE complex formation and vacuole membrane fusion (PubMed:30427760).  Hyperosmotic shock-induced increase in the levels of PtdIns(3,5)P2 requires the presence of VAC7, VAC14, and/or FIG4 (PubMed:16492811).
What are the official names of this protein?
1-phosphatidylinositol 3-phosphate 5-kinase FAB1, Phosphatidylinositol 3-phosphate 5-kinase, Formation of aploid and binucleate cells protein 1, Styryl dye vacuolar localization protein 7, Type III PIP kinase, PIPkin-III.
What are the subcellular locations of this protein?
Vacuole membrane; Peripheral membrane protein. Endosome membrane; Peripheral membrane protein. Note=Localization to the vacuole membrane requires VAC14 and FIG4.
