SARS-CoV-2 is an RNA betacoronavirus that interacts with its cellular receptor ACE2 via its spike protein during the initial step of infection (Lan et al., 2020; Matheson and Lehner, 2020; Walls et al., 2020; Wang et al., 2020; Wrapp et al., 2020). The gene discussed is ACE2; the disease is infection.
