Binds with low affinity to dsDNA and ssRNA, and with high affinity to dsRNA, with no detectable sequence specificity. Forms a heteromeric complex with XPO5 and ILF3. Found in a nuclear export complex with XPO5, RAN, ILF3, ZNF346 and double-stranded RNA. Interacts with XPO5. Interacts with ILF3 in an RNA-independent manner (By similarity). Nuclear at steady state, primarily in the nucleolus. Shuttles between the nucleus and cytoplasm when associated with XPO5 (By similarity). The zinc-finger domains are required for binding to dsRNA, and also for nuclear localization.
