COPII: A membrane coat formed by Sec proteins that drive vesicle budding from the endoplasmic reticulum
In vitro synthesis of endoplasmic reticulum-derived transport vesicles has been reconstituted with washed membranes and three soluble proteins (Sar1p, Sec13p complex, and Sec23p complex). VesicleExpand
Identification of 23 complementation groups required for post-translational events in the yeast secretory pathway
Cells of a Saccharomyces cerevisiae mutant that is temperature-sensitive for secretion and cell surface growth become dense during incubation at the non-permissive temperature (37 degrees C). ThisExpand
Bi-directional protein transport between the ER and Golgi.
The endoplasmic reticulum (ER) and the Golgi comprise the first two steps in protein secretion. Vesicular carriers mediate a continuous flux of proteins and lipids between these compartments,Expand
COPII-Coated Vesicle Formation Reconstituted with Purified Coat Proteins and Chemically Defined Liposomes
COPII vesicle formation requires only three coat assembly subunits: Sar1p, Sec13/31p, and Sec23/24p. PI 4-phosphate or PI 4,5-bisphosphate is required for the binding of these proteins to liposomes.Expand
Guidelines for the use and interpretation of assays for monitoring autophagy (3rd edition)
In 2008 we published the first set of guidelines for standardizing research in autophagy. Since then, research on this topic has continued to accelerate, and many new scientists have entered theExpand
Requirement for a GTPase-activating protein in vesicle budding from the endoplasmic reticulum.
The binding and hydrolysis of guanosine triphosphate (GTP) by the small GTP-binding protein Sar1p is required to form transport vesicles from the endoplasmic reticulum (ER) in SaccharomycesExpand
Coat Proteins and Vesicle Budding
The trafficking of proteins within eukaryotic cells is achieved by the capture of cargo and targeting molecules into vesicles that bud from a donor membrane and deliver their contents to a receivingExpand
Multiple Cargo Binding Sites on the COPII Subunit Sec24p Ensure Capture of Diverse Membrane Proteins into Transport Vesicles
We have characterized the mechanisms of cargo selection into ER-derived vesicles by the COPII subunit Sec24p. We identified a site on Sec24p that recognizes the v-SNARE Bet1p and show that packagingExpand
SEC12 encodes a guanine-nucleotide-exchange factor essential for transport vesicle budding from the ER
IN yeast a type II integral membrane glycoprotein that is essential for transport vesicle budding from the endoplasmic reticulum (ER) is encoded by SEC12 (refs 1–3). SAR1 was discovered as aExpand
Dynamics of the COPII coat with GTP and stable analogues
We have developed an assay to monitor the assembly of the COPII coat onto liposomes in real time. We show that with Sar1pGTP bound to liposomes, a single round of assembly and disassembly of theExpand
