Diminished incidence of COVID-19 amongst healthcare workers in a comprehensive screening programme demonstrates how effective infection control measures and staff testing can prevent hospitals becoming independent 'hubs' of SARS-CoV-2 transmission.
SNARE proteins are delivered as complexes already from the endoplasmic reticulum along the secretory pathway to the cell division plane to mediate the formation of the partitioning membrane by vesicle fusion.
SARS-CoV-2 has evolved to cleverly mimic the FURIN-cleavage site in human ENaC-α, unlike any prior coronavirus strain, shedding new light on the Acute Respiratory Distress Syndrome (ARDS) in COVID-19 patients.
Electron-cryomicroscopy structures of the supercomplex of NSF, αSNAP, and neuronal SNAREs in the presence of ATP under non-hydrolyzing conditions at 3.9 Å resolution reveal interactions between the N-terminal residues of SNAP-25 and NSF.
Isothermal titration calorimetry experiments clarify apparently discrepant results described previously and show that N-terminal sequences of complexin bind to SNARE complexes containing C-terminally truncated synaptobrevin when they include the syntaxin-1 juxtamembrane region.
