Coronaviruses are positive-stranded RNA viruses, featuring the largest viral RNA genomes known to date (27-31 kb). Seven coronaviruses had been found to cause human infection including SARS-CoV-2/2019-nCoV resulting in a potentially fatal atypical pneumonia, named COVID-19. SARS-CoV-2 has 4 major structural proteins including spike (S), envelope (E), membrane (M), and nucleocapsid (N), which share significant sequence homology with SARS-CoV. The spike protein in SARS-CoV-2 (1,273 aa) is a viral surface glycoprotein. Research on SARS-host protein interactions with SARS-CoV and SARS-CoV-2 viruses have shown that the viral spike (S) protein binds human ACE-2 located on the surface of mucosal cells, resulting in fusion of viral and cell membranes for viral entry. Viral entry also requires priming of the S protein by host cell proteases such as TMPRSS2, Cathepsin L or furin. The Coronavirus Spike precursor protein is processed into 2 distinct subunits with S1 (654 aa) housing the receptor binding domain (RBD) and S2 (588 aa or 458 a) facilitating membrane fusion.
