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}.
