Sequences homologous to the X box of class II MHC genes are conserved in the LTRs of different HIV-1 isolatesa
| GenBank entry | Sequence of X-like element |
|---|---|
| HIVBH101 | TGGTTAGACCAGATCTGAGC |
| HIVBH102 | TGGTTAGACCAGATCTGAGC |
| HIVBRUCG | TGGTTAGACCAGATTTGAGC |
| HIVCDC41 | TGGTTAGACCAGATCTGAGT |
| HIVHXB2CG | TGGTTAGACCAGATCTGAGC |
| HIVPV22 | TGGTTAGACCAGATCTGAGC |
| HIVSF2CG | TGGTTAGACCAGATCTGAGC |
The X box sequence of the HLA-DRA gene is AGCAACAGATG. The X box sequences in the table are shown in boldface.
