The biosynthesis of secretory proteins requires vesicle-mediated transport between the organelles of the secretory pathway. Biochemical and genetic analysis of the secretory pathway has identified two non-clathrin coats--COPI and COPII--that drive the formation of vesicles that mediate transport between the endoplasmic reticulum and the Golgi apparatus, and through the compartments of the Golgi. Recently, a molecular description of the subunits of these coats and the development of biochemical reagents to study their function has yielded new information on how these proteins share the task of organizing vesicle traffic early in the secretory pathway.
