Abstract

The HIV-1 co-receptor CCR5 possesses sulfo-tyrosine (TYS) residues at its N-terminus (Nt) that are required for binding HIV-1 gp120 and mediating viral entry. By using a 14-residue fragment of CCR5 Nt containing two TYS residues, we recently showed that CCR5 Nt binds gp120 through a conserved region specific for TYS moieties and suggested that this site may represent a target for inhibitors and probes of HIV-1 entry. As peptides containing ...
