NCIt synonyms : S Glycoprotein; S Protein; SARS-CoV-2 Spike Protein; Severe Acute Respiratory Syndrome Coronavirus 2 Spike Glycoprotein; Spike Glycoprotein; Peplomer Protein; SARS-CoV-2 S Protein; SARS2 Spike Protein; SARS2 S Protein; SARS2 Spike Glycoprotein;
NCIt related terms : Full Length Spike Trimer;
NCIt definition : Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike glycoprotein (1273
aa, 141 kDa) is encoded by the SARS-CoV-2 S gene. This protein plays a role in binding
to host cell membranes and the initiation of viral infection.;
Alternative definition : CDISC: The approximately 180-200 kDa transmembrane, receptor binding protein from
the Severe Acute Respiratory Syndrome Coronavirus 2 virus (SARS-CoV-2).;
NCIt note : SARS-CoV-2 spike glycoprotein is sequentially cleaved to form spike protein S1 (amino
acid residues 13-685), spike protein S2 (residues 686-1273) and spike protein S2'
(residues 816-1273). S1 binds to angiotensin-converting enzyme 2, while S2 and S2'
mediate fusion of the virion and cellular membranes. (UniProt);
