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). SOR protein
