Question

Quizplus · Accepted Answer

The spike protein (S protein) of the SARS coronavirus is responsible for binding to the host cell receptor, which is an important step in viral entry into the host cell. The S protein binds to the angiotensin-converting enzyme 2 (ACE2) receptor on the host cell membrane, facilitating viral entry and infection. The other proteins listed (M protein, nucleocapsid protein, RNA) do not play a direct role in binding to the host cell receptor.
