Sumario:BACKGROUND: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has caused millions of infections and deaths worldwide since its discovery in late 2019 in Wuhan, China. The receptor-binding domain (RBD) of the SARS-CoV-2 spike protein binds to the human angiotensin-converting enzyme-2 (ACE2) receptor, a critical component of the renin-angiotensin system (RAS) that initiates the viral transmission. Most of the critical mutations found in SARS-CoV-2 are associated with the RBD of the spike protein. These mutations have the potential to reduce the efficacy of vaccines and neutralizing antibodies. METHODS: In this review, the structural details of ACE2, RBD and their interactions are discussed. In addition, some critical mutations of RBD and their impact on ACE2-RBD interactions are also discussed. CONCLUSION: Preventing the interaction between Spike RBD and ACE2 is considered a viable therapeutic strategy since ACE2 binding by RBD is the first step in virus infection. Because the interactions between the two entities are critical for both viral transmission and therapeutic development, it is essential to understand their interactions in detail.
