CD4 Binding Site of HIV Envelope Glycoprotein gp120 (gp120 CD4 Binding Site)

Target
gp120 CD4 Binding Site
Molecular classification
Receptor, Glycoprotein
01

Overview

The CD4 binding site of HIV envelope glycoprotein gp120 is a critical component in the viral entry process. It binds to the CD4 receptor on host cells, inducing conformational changes that facilitate interaction with coreceptors (CCR5 or CXCR4) and subsequent fusion of viral and host membranes. This site is a major target for vaccine development and therapeutic intervention, as it is exposed and accessible to antibodies and inhibitors[1][2][3].
