COVID 19 Spike protein, Alpha Variant of Concern, B.1.1.7 variant Coronavirus Recombinant Protein
Recombinant SARS-CoV-2 Spike protein, Alpha Variant of Concern, B.1.1.7 variant (United Kingdom, HV69-70del, Y144del, N501Y, A570D, D614G, P681H, T716I, S982A and D1118H)
The first reports of atypical pneumonia in China were announced at the very end of 2019, in the city of Wuhan, Hubei province. Its cause was identified in January 2020 as a novel ?-CoV (1), named SARS-CoV-2, which started spreading very quickly causing a global pandemic COVID-19. Spike protein attaches the virion to the cell membrane by interacting with host receptor, initiating the infection. Binding to human ACE2 receptor and internalization of the virus into the endosomes of the host cell induces conformational changes in the Spike glycoprotein (2, 3). The protein forms a trimer in vivo mediating receptor binding and membrane fusion (4). It has been demonstrated by Florian Krammer’s group that certain mutations and the inclusion of trimerization motif can stabilize recombinant Spike protein (5, 6). The original Wuhan strain of the virus has become quickly replaced by its more transmissible variant, mainly determined by a single amino acid point mutation D614G (7). The B.1.1.7 variant is a strain of the coronavirus with 8 distinctive mutations (in addition to the D614G) in the virus's spike protein and was first identified in autumn 2020 as the result of genetic sequencing of positive covid-19 samples by the Covid-19 Genomics UK Consortium (8).
