| Enzyme Function | FUNCTION: Counteracts the innate antiviral activity of APOBEC3G. Forms a complex with host APOBEC3G thus preventing the entry of this lethally hypermutating enzyme into progeny virions. Functions as an adapter molecule, recruiting APOBEC3G to the ubiquitin-proteasome machinery. Targets APOBEC3G for degradation through the assembly with elongin BC complex, CUL5 and RBX1. Binds viral RNA and affects the stability of viral nucleoprotein core. May play a role in viral morphology (By similarity). {ECO:0000250}. |

| Induction | INDUCTION: Expressed late during infection in a Rev-dependent manner. |
| Subcellular Location | SUBCELLULAR LOCATION: Host cytoplasm {ECO:0000250}. Host cell membrane {ECO:0000250}; Peripheral membrane protein {ECO:0000250}; Cytoplasmic side {ECO:0000250}. Virion {ECO:0000250}. Note=Seems to colocalize with intermediate filament vimentin. A fraction is associated with the cytoplasmic side of cellular membranes, presumably via the interaction with Pr55Gag precursor (By similarity). {ECO:0000250}. |
