The following text describes a protein:
Function:
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. Required for endocytic-vacuolar pathway and nuclear migration. 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. PI(3,5)P2 regulates the transition between trans-SNARE complex formation and vacuole membrane fusion. Hyperosmotic shock-induced increase in the levels of PtdIns(3,5)P2 requires the presence of VAC7, VAC14, and/or FIG4.
Miscellaneous:
MISCELLANEOUS: Present with 149 molecules/cell in log phase SD medium.
Subcellular Localization:
Vacuole membrane; Peripheral membrane protein. Endosome membrane; Peripheral membrane protein. Note=Localization to the vacuole membrane requires VAC14 and FIG4.
Domain:
The chaperone-containing TCP1 (CCT) domain is essential for the interaction with the scaffold protein VAC14; The conserved cysteine-rich (CCR) domain contacts intramolecularly the C-terminus, including the kinase domain, and this interaction negatively regulates PI(3) 5-kinase activity.
