Yeast PI(3,4,5)P3 controls vacuole fusion through Vam7 and membrane microdomain assembly

Chi Zhang, Jorge D. Calderin, Vito Failla…·Rutilio A. Fratti

This study identifies PI(3,4,5)P3 as a regulator of yeast vacuole fusion, showing it controls vertex microdomain assembly and retains the SNARE Vam7 on membranes.
