Table 3 Structural proteins of coronavirus and their functions
From: COVID-19 pandemic crisis—a complete outline of SARS-CoV-2
Structural proteins | Functions of proteins |
|---|---|
Spike protein (S) | Virus and host cell fusion by binding |
Membrane protein (M) | Nutrient transport, determines shape, and formation of envelope |
Envelope protein (E) | Interferes with host immune response |
Nucleocapsid protein (N) | Binds with RNA genome and makes up nucleocapsid |
Hemagglutinin-esterase (HE) | Binds sialic acids on surface glycoprotein |
