SARS-CoV-2 Spike GlycoProtein 1220-1228 is the 1220-1228 amino acid residue of SARS-CoV-2 Spike GlycoProtein. SARS-CoV-2 Spike GlycoProtein is composed of S1 and S2 subunits. The S1 subunit contains a receptor-binding domain that recognizes and binds to the host receptor angiotensin-converting enzyme 2, while the S2 subunit mediates viral cell membrane fusion by forming a six-helical bundle via the two-heptad repeat domain.
