The human immunodeficiency virus type 1 Rev protein contains a nuclear export signal (NES) that is required for Rev-mediated RNA export in mammals as well as in the yeast Saccharomyces cerevisiae. The Rev NES has been shown to specifically interact with a human (hRIP/RAB1) and a yeast (yRip1p) protein in the two-hybrid assay. Both of these interacting proteins are related to FG nucleoporins on the basis of the presence of typical repeat motifs. This paper shows that Rev is able to interact with multiple FG repeat-containing nucleoporins from both S. cerevisiae and mammals; moreover, the ability of Rev NES mutants to interact with these FG nucleoporins parallels the ability of the mutants to promote RNA export in yeast and mammalian cells. The data also show that, after Xenopus oocyte nuclear injection, several FG nucleoporin repeat domains inhibit the export of both Rev protein and U small nuclear RNAs, suggesting that these nucleoporins participate in Rev-mediated and cellular RNA export. Interestingly, not all FG nucleoporin repeat domains produced the same pattern of RNA export inhibition. The results suggest that Rev and cellular mediators of RNA export can interact with multiple components of the nuclear pore complex during transport, analogous to the proposed mode of action of the nuclear protein import receptor.
