The initial step of SARS‐CoV‐2 infection is binding of the viral Spike protein to Angiotensin‐converting enzyme 2 (ACE2) (Shang et al, 2020; Wang et al, 2020; Zhou et al, 2020), followed by proteolytic processing of the trimeric Spike (Benton et al, 2020; Hoffmann et al, 2020) and subsequent infection of target cells (Hu et al, 2021). This evidence concerns the gene ACE2 and infection.
