A flurry of recent papers report structural results on proteins that are essential for membrane fusion during exocytosis, providing a starting point from which a mechanistic understanding of ...

Assembly and budding of a virus from a membrane microdomain. Viruses have an outer protein shell called a capsid which surrounds the viral nucleic acid. Enveloped viruses, such as HIV, have an ...

Many phylogenetically distant animal viruses, including the new coronavirus SARS-CoV-2, have surface proteins with polybasic sites that are cleaved by host furin and furin-like proteases. Other than ...
