WebWe tested the hypothesis that E1 is a truncated class II fusion protein. We mutated amino acids within a predicted fusion peptide (residues 276-286) and a truncated C-terminal stem-like motif, containing a membrane-proximal heptad-repeat sequence (residues 330-347). WebViral fusion proteins are key components of virus particles that enable a virus to enter an animal host cell. Fusion proteins are the most common targets for neutralizing antibodies and serve a vital role as vaccine immunogens to elicit a protective immune response. To develop an understanding of SARS-CoV-2 antibody-mediated neutralization, one ...
