And here is a succinct explanation of the different Coronavirus proteins...
Coronaviruses are enveloped positive-stranded RNA viruses that belong to the Coronaviridae family in the Nidovirales order. The virion envelope contains at least three structural proteins, the membrane (M), spike (S), and envelope (E) proteins. The genomic RNA is encapsidated by the N phosphoprotein to form a helical nucleocapsid. The S glycoprotein is the viral attachment protein that facilitates infection through fusion of viral and cellular membranes and is the major target of neutralizing antibodies (13). The M glycoprotein is the most abundant component of the viral envelope and plays required, key roles in virus assembly (9, 20, 31, 33, 41). The E protein is a minor component of the viral envelope that plays an important, not clearly defined, role(s) during virus assembly and release (2, 5, 41).
So my question is essentially what if any relationship is there between Biotron's work with the E protein and the discoveries announced today that refer to the S protein?
