Notably, SARS-CoV-2 shared 79% sequence identify to SARS-CoV (Severe acute respiratory syndrome coronavirus) and they may both share the ACE2 as host receptor according to structural analyses.[4] SARS-CoV uses ACE2 as one of the main receptors for the entry into the host cells which plays a crucial role in the disease infection.[5] The target towards the interaction between the virus and receptor may be able to treat the disease. This evidence concerns the gene ACE2 and infection.
