HIV Envelope Glycoprotein gp120 (gp120)

Target
gp120
Molecular classification
Glycoprotein, Viral Envelope Protein
01

Overview

gp120 is a glycoprotein exposed on the surface of the HIV envelope, essential for virus entry into host cells. It binds to CD4 receptors and chemokine co-receptors CCR5 or CXCR4 on host cells, initiating the membrane fusion process. The extensive glycan shield and sequence variability contribute to immune evasion, making it a challenging target for therapeutic intervention.
