Participates in a multitude of cellular RNA processing and degradation events preventing nuclear export and/or translation of aberrant RNAs. Restricted to processing linear and circular single-stranded RNAs (ssRNA) only. RNAs with complex secondary structures may have to be unwound or pre-processed by co-factors prior to entering the complex, esp if the 3-prime end is structured.

    GO:0000061    protein import into nucleus, substrate release    A protein complex disassembly process that contributes to protein import into the nucleus, and that results in the dissociation of the cargo protein and the carrier (such as an importin alpha/beta heterodimer) from each other and from the nuclear pore complex.
