Human Immunodeficiency Virus Type 1 Envelope Glycoprotein (Env)
- Target
- Env
- Molecular classification
- Glycoprotein, Viral protein, Fusion protein
01
Overview
The HIV-1 envelope glycoprotein (Env) is an oligomeric complex critical for virus entry via receptor-mediated attachment and membrane fusion. It consists of two subunits—gp120 (binding) and gp41 (fusion)—derived from cleavage of precursor protein gp160. Its structural complexity, heavy glycosylation, conformational flexibility, and central role in immune evasion make it both challenging as a vaccine target yet indispensable for effective intervention strategies against HIV infection.
