Lipid Regulated Intramolecular Conformational Dynamics of SNARE-Protein Ykt6
Cellular informational and metabolic processes are propagated with specific membrane fusions governed by soluble N-ethylmaleimide sensitive factor attachment protein receptors (SNARE). SNARE protein Ykt6 is highly expressed in brain neurons and plays a critical role in the membrane-trafficking process. Studies suggested that Ykt6 undergoes a conformational change at the interface between its lo...
متن کاملComplexin induces a conformational change at the membrane-proximal C-terminal end of the SNARE complex
Complexin regulates spontaneous and activates Ca(2+)-triggered neurotransmitter release, yet the molecular mechanisms are still unclear. Here we performed single molecule fluorescence resonance energy transfer experiments and uncovered two conformations of complexin-1 bound to the ternary SNARE complex. In the cis conformation, complexin-1 induces a conformational change at the membrane-proxima...
متن کاملAPOL1 variants change C-terminal conformational dynamics and binding to SNARE protein VAMP8.
APOL1 variants in African populations mediate resistance to trypanosomal infection but increase risk for kidney diseases through unknown mechanisms. APOL1 is expressed in glomerular podocytes and does not vary with underlying kidney disease diagnoses or APOL1 genotypes, suggesting that the kidney disease-associated variants dysregulate its function rather than its localization or abundance. Str...
متن کاملAutoinhibition of SNARE complex assembly by a conformational switch represents a conserved feature of syntaxins.
Regulation and specificity of membrane trafficking are required to maintain organelle integrity while performing essential cellular transport. Membrane fusion events in all eukaryotic cells are facilitated by the formation of specific SNARE (soluble N-ethylmaleimide-sensitive fusion protein-attachment protein receptor) complexes between proteins on opposing lipid bilayers. Although regulation o...
متن کاملA Novel Site of Action for -SNAP in the SNARE Conformational Cycle Controlling Membrane Fusion
Regulated exocytosis in neurons and neuroendocrine cells requires the formation of a stable soluble N-ethylmaleimidesensitive factor attachment protein receptor (SNARE) complex consisting of synaptobrevin-2/vesicle-associated membrane protein 2, synaptosome-associated protein of 25 kDa (SNAP-25), and syntaxin 1. This complex is subsequently disassembled by the concerted action of -SNAP and the ...
