The V1V2 Domain and an N-Linked Glycosylation Site in the V3 Loop of the HIV-1 Envelope Glycoprotein Modulate Neutralization Sensitivity to the Human Broadly Neutralizing Antibody 2G12

Abstract excerpt

The broadly neutralizing human monoclonal antibody 2G12 binds to a carbohydrate-dependent epitope involving three major potential N-linked glycosylation sites (PNGS) of gp120 (N295, N332, and N392). Through analysis of the sensitivity to 2G12 of pseudotyped viruses carrying envelope proteins from HIV-1 clade B-infected long-term nonprogressors, we selected two naturally occurring env clones with opposite...
