The envelope glycoprotein Gp160 of HIV1 is cleaved into the surface protein Gp120 and the transmembrane protein Gp41. 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].	Domain
