Figure 2From: Modelling binding between CCR5 and CXCR4 receptors and their ligands suggests the surface electrostatic potential of the co-receptor to be a key player in the HIV-1 tropismPepSite scores of V3 loop sequences. PepSite scores for a 10-amino acid sliding window reflect the propensities of R5-tropic and X4-capable sequences to bind to CXCR4. A: experimentally verified sequences; B: predicted sequences. P-values displayed are based on a two-sided Wilcoxon test.Back to article page
