FIG 1.

Sequences and localization of putative antisense proteins (ASP) in the HIV genome. (A) The full-length HIV genome is shown with structural and accessory proteins encoded in the three regular open reading frames (ORFs). Black boxes depict the location of the five predicted ASPs relative to the regular ORFs. (B) The consensus amino acid sequences of the five predicted proteins are shown. Their antisense reading frames (ASRFs) and the frequencies at which they were found among 355 HIV isolates are indicated. *, stop codon.
