This paper entailed state-of-the-art experimental procedures to explore the binding of the Y674-R685 loop of the SARS-CoV-2 S-protein to three nAChRs – namely the human α4β2 and α7 subtypes ...

The entire S1 domain (Gln-14 to Arg-685) containing both Y674 –R685 and S375-L390 peptides was tested, which had a similar result; however, the [125 I]-a-BgTx-receptor-binding was not notably ...
