Schematic representation of the Spike glycoprotein S1/S2 subunit of SARS-CoV-2 and the localization of peptides used in the study. Variability of the peptide sequence in the S2 subunit for SARS-CoV-2, including SARS-CoV-2 variants (Table 2s) used in this study pango lineage B.1 (Wuhan-like with the mutation G614D), B.1.1.7 (Alpha), B.1.617.2 (Delta), BA.1 (Omicron), SARS-CoV, bat SARS-like CoV and Pangolin CoV are also showed. Underline sequence represent region of peptide used in other study (Liao et al., 2015). NTD, N-terminal domain, RBD, receptor binding domain, FP, fusion peptide, FPPR, Fusion peptide proximal region, IFP, internal fusion peptide, HR1, heptad repeat 1, HR2, heptad repeat 2, MPER, membrane proximal region, TM, transmembrane region, Cyto, cytoplasmic region.
