Vacuole morphology and inheritance protein 14

Gene

VAC14

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

The PI(3,5)P2 regulatory complex regulates both the synthesis and turnover of phosphatidylinositol 3,5-bisphosphate (PtdIns(3,5)P2). Regulates the synthesis of PtdIns(3,5)P2 by positive activation of FAB1 and by controlling FIG4 localization. Required for FIG4-mediated turnover of PtdIns(3,5)P2 after hyperosmotic shock. Essential for the control of trafficking of some proteins to the vacuole lumen via the multivesicular body (MVB), and for maintenance of vacuole size and acidity.5 Publications
