The entry of HIV requires interaction of viral GP120 with the CD4 glycoprotein (Swiss:P01730) and a chemokine receptor on the cell surface [1]. Gp160 us proteolytically cleaved n the trans-Golgi and activated by cellular furin or furin-like proteases to produce gp120 and gp41 [1,2].

They share several motifs, mainly the seven transmembrane helices, GCPRs of the rhodopsin superfamily. All opsins bind a chromophore, such as 11-cis-retinal. The function of most opsins other than the photoisomerases is split into two steps: light absorption and G-protein activation. Photoisomerases, on the other hand, are not coupled to G-proteins - they are thought to generate and supply the chromophore that is used by visual opsins [1].
