CC   -!- FUNCTION: Escorts unspliced or incompletely spliced viral pre-mRNAs
CC       (late transcripts) out of the nucleus of infected cells. These pre-
CC       mRNAs carry a recognition sequence called Rev responsive element (RRE)
CC       located in the env gene, that is not present in fully spliced viral
CC       mRNAs (early transcripts). This function is essential since most viral
CC       proteins are translated from unspliced or partially spliced pre-mRNAs
CC       which cannot exit the nucleus by the pathway used by fully processed
CC       cellular mRNAs (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Homomultimer; when bound to the RRE. Multimeric assembly is
CC       essential for activity (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Host nucleus, host nucleolus. Host cytoplasm.
CC       Note=The presence of both nuclear import and nuclear export signals
CC       leads to continuous shuttling between the nucleus and cytoplasm.
CC       {ECO:0000250}.
CC   -!- DOMAIN: The RNA-binding motif binds to the RRE, a stem-and-loop
CC       structure present in incompletely spliced viral pre-mRNAs. This region
CC       also contains the NLS which mediates nuclear localization. These
CC       overlapping functions prevent Rev bound to RRE from undesirable return
CC       to the nucleus. When Rev binds the RRE, the NLS becomes masked while
CC       the NES remains accessible (By similarity). {ECO:0000250}.
