 AB    Replication of human immunodeficiency virus type 1 (HIV-1) is dependent
       on the viral Rev protein. This protein acts in concert with the
       cis-acting rev-responsive element present in intron-containing RNAs to
       facilitate nuclear export of these RNAs. Here we show that a cis-acting
       219-nucleotide sequence from an unrelated simple retrovirus,
       Mason-Pfizer monkey virus (MPMV), enables Rev-independent HIV-1
       replication. This sequence is present in an untranslated region near the
       3' end of the MPMV genome. The MPMV element is also able to efficiently
       substitute for Rev in expression of Gag/Pol and Env proteins from
       subgenomic constructs. We hypothesize that the MPMV element functions by
       interacting with a cellular factor that plays a role in mRNA transport
       analogous to that of the Rev protein. It might be possible to exploit
       this element in the development of an HIV vaccine.
