McKeating1993a J. A. McKeating, C. Shotton, J. Cordell, S. Graham, P. Balfe, N. Sullivan, M. Charles, M. Page, A. Bolmstedt, S. Olofsson, S. C. Kayman, Z. Wu, A. Pinter, C. Dean, J. Sodroski, and R. A. Weiss. Characterization of neutralizing monoclonal antibodies to linear and conformation-dependent epitopes within the first and second variable domains of human immunodeficiency virus type 1 gp120. J. Virol., 67:4932-4944, 1993. Substitutions in the V2 loop can result in complete dissociation of gp120 and gp41, suggesting alterations in V2 can affect subunit assembly. Other substitutions allowed gp120-gp41 association and expression, but inhibited viral entry or syncytia. Binding of some neutralizing MAbs was altered by V2 substitutions. For MAb CRA-4, changes at residues 191/192/193 (YSL/GSS), and for 11/68b, changes at residues 183/184 (PI/SG), within V2, and for both MAbs a position 435 (Y/H) change in C4, abrogate binding. These MAbs can bind to V1 and V2 domains in the absence of C4 domain, so the C4 substitution probably results in conformational change. PubMed ID: 7687306. Show all entries for this paper.

Shotton1995 C. Shotton, C. Arnold, Q. Sattentau, J. Sodroski, and J. A. McKeating. Identification and characterization of monoclonal antibodies specific for polymorphic antigenic determinants within the V2 region of the human immunodeficiency virus type 1 envelope glycoprotein. J. Virol., 69:222-230, 1995. Anti-V2 linear and conformation dependent MAbs were studied. All V2 Abs studied could bind IIIB, but failed to neutralize non-clonal stocks. Epitope exposure is different in rgp120 compared to native gp120. HXB2 V2-MAb neutralization escape mutants were sequenced. PubMed ID: 7527084. Show all entries for this paper.
