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