ACE2 is also an important receptor for SARS-CoV-2; however, other receptors have been critically proposed to mediate infections such as neuropilin-1 (Cantuti-Castelvetri et al., 2020; Daly et al., 2020) or CD147 (Wang et al., 2020a, Wang et al., 2020b). The gene discussed is BSG; the disease is infection.
