Conservation of the Nuclear Receptor Response Element in HIV-1 LTRs: A Possible PPAR Response Element?

Figure 4

The NRRE-1-DE in the 5′-LTR of HIV-1 isolates from Tanzania. (a) The alignment of the 5′-LTR sequences from the beginning of the sequence provided, with the location of the NRRE-1-DE indicated above the sequences. The alignment was coloured with Boxshade, with identical nucleotides shown in black and similar nucleotides shown in grey. (b) Sequence logo of the NRRE-1-DE in the HIV-1 5′-LTR isolates from Tanzania, showing conservation of the nucleotide sequence in most positions but with degeneracy in nucleotide positions 62 and 65. The colour scheme is as indicated above for Figure 2. The GenBank accession numbers for the source sequences are AF254673.1–AF254736.1.
