| + | </br> | ||
| + | The dynamic epidemiology of coronavirus disease 2019 (COVID-19) since its outbreak has been a result of the continuous evolution of its etiological agent, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Within the first 2 years of this pandemic, the World Health Organization (WHO) has already announced 4 variants of concern (VOC), namely alpha (B.1.1.7), beta (B.1.351), gamma (P.1), and delta (B.1.617.2), together with numerous variants of interest (VOI). The latest lineage to be designated a VOC would be omicron (B.1.1.529),<ref name="Karim" /> from which a diverse variant soup is generated.<ref>Callaway, E. COVID ‘variant soup’ is making winter surges hard to predict.

Recent emerging variant (EV) data retrieved from GISAID, as of 17 January 2023, has revealed that the top 4 most rapidly spreading lineages are the BA.1.1.22, CH.1.1, XBB.1.5, and BQ.1.1 variants, among which XBB.1.5 has been found to be especially prevalent in the US,<ref>Callaway, E.

| + | ==Spike Glycoprotein== | ||
| + | The spike glycoprotein of SARS-CoV-2 is a trimeric type I viral fusion protein that binds the virus to the angiotensin-converting enzyme 2 (ACE2) receptor of a host cell.<ref name="Jackson2021"/> It is composed of 2 subunits: the N-terminal subunit 1 (S1) and C-terminal subunit 2 (S2), within which multiple domains lie. The S1 region facilitates ACE2 binding and is made up of an N-terminal domain (NTD), a receptor-binding domain (RBD), and 2 C-terminal subdomains (CTD1 and CTD2), while the downstream S2 region is responsible for mediating virus-host cell membrane fusion. | ||

Dynamic Expedition of Leading Mutations in SARS-CoV-2 Spike Glycoproteins
The dynamic epidemiology of coronavirus disease 2019 (COVID-19) since its outbreak has been a result of the continuous evolution of its etiological agent, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Within the first 2 years of this pandemic, the World Health Organization (WHO) has already announced 4 variants of concern (VOC), namely alpha (B.1.1.7), beta (B.1.351), gamma (P.1), and delta (B.1.617.2), together with numerous variants of interest (VOI). The latest lineage to be designated a VOC would be omicron (B.1.1.529),[1] from which a diverse variant soup is generated.[2] From the original BA.1 strain of November 2021 to the most recent XBB and BQ.1 strains of late 2022,[3][4] each omicron subvariant has successively proliferated and outcompeted its once dominant antecedent.[5] The emergence of all these variants has brought along many novel mutations that continue to fine-tune the fitness of the virus,[6][7] leading to its persistent global circulation. Recent emerging variant (EV) data retrieved from GISAID, as of 17 January 2023, has revealed that the top 4 most rapidly spreading lineages are the BA.1.1.22, CH.1.1, XBB.1.5, and BQ.1.1 variants, among which XBB.1.5 has been found to be especially prevalent in the US,[8] making up of more than 40% of its sequence coverage in early January 2023.
Spike Glycoprotein
The spike glycoprotein of SARS-CoV-2 is a trimeric type I viral fusion protein that binds the virus to the angiotensin-converting enzyme 2 (ACE2) receptor of a host cell.[9] It is composed of 2 subunits: the N-terminal subunit 1 (S1) and C-terminal subunit 2 (S2), within which multiple domains lie. The S1 region facilitates ACE2 binding and is made up of an N-terminal domain (NTD), a receptor-binding domain (RBD), and 2 C-terminal subdomains (CTD1 and CTD2), while the downstream S2 region is responsible for mediating virus-host cell membrane fusion.
