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}. CC -!- MISCELLANEOUS: This isolate is from a Gambian case of 'neuro-AIDS'.
