      Background InformationSpike glycoprotein (UniProt: P59594; also known as S glycoprotein, E2, Peplomer protein) is encoded by the S (also known as 2) gene (Gene ID: 1489668) in SARS-CoV-2 virus. The SARS-CoV-2 is a positive-strand RNA virus that causes severe respiratory syndrome in human. The mature SARS-CoV-2 contains 4 structural proteins: Envelope (E), Membrane (M), Nucleocapsid (N), and the Spike protein (S). E and M proteins help in viral assembly and N protein is needed for RNA synthesis. The S protein is a single-pass type I, homotrimeric, membrane glycoprotein that is responsible for virus binding and entry into host cell. It is synthesized with a signal peptide (aa 1-12), which is subsequently cleaved off to generate the mature protein that contains an extracellular domain (aa 13-1213), a transmembrane domain (aa 1214-1234), and a cytoplasmic domain 1235-1273). The S protein is further processed into S1 (aa 13-685) and S2 (aa 686-1273) subunits by host cell furin. The presence of a furin polybasic cleavage site in S protein from SARS-CoV-2 sets it apart from S protein in SARS-CoV that possesses a monobasic S1/S2 cleavage site. The S1 subunit has the receptor binding domain (RBD; aa 319-541) that mediates entry of SARS-CoV-2 into sensitive cells through the peptidase domain of host Angiotensin-converting enzyme 2 (ACE2) with high affinity (KD = 15 nM). The S2 protein, which is reported to be well conserved, is responsible for membrane fusion. Clone 7G12 is a non-neutralizing antibody that specifically binds to the S1 subunit of SARS-CoV spike protein. It recognizes the spike protein (S delta 3).
