Function of spike protein
Web4 hours ago · The spike protein (S) has 1273 amino acids and two sub-units (S1 and S2); its primary function is binding the virus with the host cell. The nucleocapsid protein (N) has 419 amino acids and two domains (RNA-binding domain and dimerization domain), allowing for the packing of the viral RNA. WebThe spike (S) protein of SARS-CoV-2, which plays a key role in the receptor recognition and cell membrane fusion process, is composed of two subunits, S1 and S2. 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 ...
