Fig. 4From: Susceptibility of bovine to SARS-CoV-2 variants of concern: insights from ACE2, AXL, and NRP1 receptorsSequence alignment of S protein from three SARS-CoV-2 strains, including Wuhan-Hu-1 (GenBank accession no. YP_009724390), delta variant (GenBank accession no. QYM88683), and omicron variant (GenBank accession no. UFS23237). A The important residues in RBD of S interacting with ACE2 and NRP1 are marked with green stars. B The important residues in NTD of S interacting with AXL are marked with green starsBack to article page
