Functional and immunologic characterization of human immunodeficiency virus type 1 envelope glycoproteins containing deletions of the major variable regions.

Abstract excerpt

Deletions of the major variable regions (V1/V2, V3, and V4) of the human immunodeficiency virus type 1 (HIV-1) gp120 exterior envelope glycoprotein were created to study the role of these regions in function and antigenicity. Deletion of the V4 region disrupted processing of the envelope glycoprotein precursor. In contrast, the deletion of the V1/V2 and/or V3 regions yielded processed exterior envelope...
