Exo70p mediates the secretion of specific exocytic vesicles at early stages of the cell cycle for polarized cell growth.

The Journal of cell biology - 12 Mar 2007

Abstract excerpt

In budding yeast, two classes of post-Golgi secretory vesicles carrying different sets of cargoes typified by Bgl2p and invertase are delivered to the plasma membrane for secretion. The exocyst is implicated in tethering these vesicles to the daughter cell membrane for exocytosis. In this study, we report that mutations in the exocyst component Exo70p predominantly block secretion of the Bgl2p vesicles....
