CC   -!- FUNCTION: Stimulates gene expression driven by the HIV-2 LTR. Prevents
CC       infected cells from undergoing mitosis and proliferating, by inducing
CC       arrest or delay in the G2 phase of the cell cycle. Cell cycle arrest
CC       creates a favorable environment for maximizing viral expression and
CC       production (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Interacts with human UNG. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Virion. Host nucleus {ECO:0000250}.
