What is a Polybasic Cleavage Site? - News-Medical.net

WebOne notable feature of the SARS-CoV-2 genome, the spike (S) protein of SARS-CoV-2 has a polybasic furin cleavage site (FCS) at its S1-S2 boundary through the insertion of 12 nucleotides encoding four amino acid residues PRRA. Quite intriguingly, this polybasic FCS is absent in coronaviruses of the same clade as SARS-CoV-2.
