The SARS-CoV-2 spike proteins play a central role in infecting our human cells, and it is a target for both antibodies and vaccine designers. To support this message users can study a real Spike protein from the SARS-CoV-2 virus scanned using cutting edge CRYO Electron Microscope technology.
The S proteins work like keys to enter living cells. If the virus finds the right cell in the right species, these keys can unlock the cell and enter.
The spike proteins on SARS-CoV-2 can enter and infect cells located in our human respiratory tracts, in areas such as the nose, throat, airways and lungs. The infection causes the respiratory disease we know as COVID-19.
