Sec24C/D-isoform–specific sorting of the preassembled ER–Golgi Q-SNARE complex

Secretory proteins are exported from the endoplasmic reticulum in COPII vesicles. SNARE proteins-core machinery for membrane fusion-are incorporated into COPII vesicles by direct interaction with Sec24. Here we report a novel mechanism for sorting of the ER-Golgi Q-SNAREs into COPII vesicles. Different mammalian Sec24 isoforms recruit either the R-SNARE Sec22b or the Q-SNAREs Syntaxin5, GS27, a...

Identification of a preassembled TRH receptor-G(q/11) protein complex in HEK293 cells.

Protein-protein interactions define specificity in signal transduction and these interactions are central to transmembrane signaling by G-protein-coupled receptors (GPCRs). It is not quite clear, however, whether GPCRs and the regulatory trimeric G-proteins behave as freely and independently diffusible molecules in the plasma membrane or whether they form some preassociated complexes. Here we u...

Structural Basis of the Intracellular Sorting of the SNARE VAMP7 by the AP3 Adaptor Complex

VAMP7 is involved in the fusion of late endocytic compartments with other membranes. One possible mechanism of VAMP7 delivery to these late compartments is via the AP3 trafficking adaptor. We show that the linker of the δ-adaptin subunit of AP3 binds the VAMP7 longin domain and determines the structure of their complex. Mutation of residues on both partners abolishes the interaction in vitro an...

Conserved structural features of the synaptic fusion complex: SNARE proteins reclassified as Q- and R-SNAREs.

SNARE [soluble NSF (N-ethylmaleimide-sensitive fusion protein) attachment protein receptor] proteins are essential for membrane fusion and are conserved from yeast to humans. Sequence alignments of the most conserved regions were mapped onto the recently solved crystal structure of the heterotrimeric synaptic fusion complex. The association of the four alpha-helices in the synaptic fusion compl...

-independent SNARE Complex Interaction

Synaptotagmins are synaptic vesicle-associated, phospholipid-binding proteins most commonly associated with Ca 1 2 -dependent exocytotic and Ca 1 2 independent endocytotic events. Synaptotagmin III is a 63.2-kD member of the synaptotagmin homology group; one of its characteristic properties is the ability to bind divalent cations and accessory proteins promiscuously. In the cytosolic portion of...
