Abstract
Antigen binding proteins of the invention bind to Human Immunodeficiency Virus (HIV) envelope protein and are useful in treating and preventing HIV infection. In particular, the antigen binding proteins bind to two different epitopes on HIV envelope surface glycoprotein 120 (gp120): the V3 loop region and the CD4 binding site.
Claims10
A nucleic acid sequence that encodes an anti-HIV gp120-binding protein having two identical heavy chains and two identical light chains, comprising or consisting of:
- a heavy chain that is at least 95% identical to SEQ ID NO:
- 121 and
- a light chain that is at least 95% identical to SEQ ID NO:63,
- wherein the two heavy chains comprise a CDRH1 of SEQ ID NO:22, a CDRH2 of SEQ ID NO:
- 23, a CDRH3 of SEQ ID NO:24, and the two light chains comprise a CDRL1 of SEQ ID NO:25, a CDRL2 of SEQ ID NO:26 and a CDRL3 of SEQ ID NO:27.
2 more elements
A host cell that comprises two expression vectors:
- a first expression vector comprising a first nucleic acid sequence encoding a heavy chain of SEQ ID NO:
- 121;
- and
- a second expression vector comprising a second nucleic acid sequence encoding a light chain of SEQ ID NO:63.
