Frontiers | MSH3 Homology and Potential Recombination Link to SARS-CoV-2 Furin Cleavage Site | Virology
Among numerous point mutation differences between the SARS-CoV-2 and the bat RaTG13 coronavirus, only the 12-nucleotide furin cleavage site (FCS) exceeds 3 nucleotides. A BLAST search revealed a 100% complementary match to the human mut S homologue (
