Protein Secretion and Vesicle Traffic by Randy Schekman - Part 1: Genetic Dissection of the Secretory Pathway (36:35)

submitted by: video_collector
Protein secretion is executed by a cellular pathway involving the delivery of membrane and soluble secretory proteins in vesicles that capture newly-synthesized proteins assembled in the endoplasmic reticulum (ER) and sorted in the Golgi apparatus. Vesicles fuse with the plasma membrane resulting in the discharge of soluble molecules to the cell exterior and integration of vesicle membrane proteins and lipids in the cell surface. Baker's yeast cells grow by vesicle fusion and secretion at...
