SARS-CoV-2, the spike (S) protein and its receptor binding-domain (RBD). (A) Coronaviruses have their name because they are decorated by prominent S proteins (yellow/green). It is the only viral protein that interacts with host cells and is the most diverging protein between different coronaviruses, particularly in its receptor binding-domain (RBD, green). RBD binds to angiotensin converting enzyme 2 (ACE2, not shown) on the host’s cell surface. The fusion peptide (FP) fuses with the host cell membrane. Specific antibodies against RBD and FP can neutralize SARS-CoV-2 NTD/CTD, N-/C-terminal domains. (B) RBD is glycosylated and methylated, which may hinder the induction of neutralizing antibodies. In contrast, the receptor interaction site (RIS, green) is not glycosylated.
