Is also involved in ribosome biogenesis. Associates with pre-60S subunits in the nucleus and is involved in its nuclear export. Cytoplasmic release of TIF6 from 60S subunits and nuclear relocalization is promoted by the GTPase RIA1/EFL1 and by SDO1.

Under normal, rapid growth conditions, high levels of NSA2 would allow the progression of pre-60S particles through the ITS2 processing.<ref>PMID:16544271</ref> <ref>PMID:16861225</ref> [[http://www.uniprot.org/uniprot/RRS1_YEAST RRS1_YEAST]] Required for ribosome biogenesis.<ref>PMID:10688653</ref> [[http://www.uniprot.org/uniprot/MRT4_YEAST MRT4_YEAST]] Involved in mRNA turnover and ribosome assembly.

Cofactor for the exosome complex that unwinds secondary structure in pre-rRNA. Required for nucleocytoplasmic transport of mRNA. May serve as a chaperone which translocates or normalizes the structure of mRNAs in preparation for export. Component of the TRAMP complex which has a poly(A) RNA polymerase activity and is involved in a post-transcriptional quality control mechanism limiting inappropriate expression of genetic information. Polyadenylation is required for the degradative activity of the exosome on several of its nuclear RNA substrates.<ref>PMID:15828860</ref> [[http://www.uniprot.org/uniprot/RPF2_YEAST RPF2_YEAST]] Required for biogenesis of the 60S ribosomal subunit.<ref>PMID:12702244</ref> [[http://www.uniprot.org/uniprot/NUG1_YEAST NUG1_YEAST]] GTPase required for 60S ribosomal subunit export to the cytoplasm.<ref>PMID:11583615</ref> [[http://www.uniprot.org/uniprot/RRP6_YEAST RRP6_YEAST]] Nuclear-specific catalytic component of the RNA exosome complex which has 3'->5' exoribonuclease activity and participates in a multitude of cellular RNA processing and degradation events. In the nucleus, the RNA exosome complex is involved in proper maturation of stable RNA species such as rRNA, snRNA and snoRNA, in the elimination of RNA processing by-products and non-coding 'pervasive' transcripts, such as antisense RNA species and cryptic unstable transcripts (CUTs), and of mRNAs with processing defects, thereby limiting or excluding their export to the cytoplasm. The catalytic inactive RNA exosome core complex of 9 subunits (Exo-9) is proposed to play a pivotal role in the binding and presentation of RNA for ribonucleolysis, and to serve as a scaffold for the association with catalytic subunits and accessory proteins or complexes. RRP6 has 3'-5' exonuclease activity which is not modulated upon association with Exo-9 suggesting that the complex inner RNA-binding path is not used to access its active site.<ref>PMID:9582370</ref> <ref>PMID:10465791</ref> <ref>PMID:10611239</ref> <ref>PMID:15489286</ref> [[http://www.uniprot.org/uniprot/RL5_YEAST RL5_YEAST]] Binds 5S RNA and is required for 60S subunit assembly. | | [https://www.uniprot.org/uniprot/RL2A_YEAST RL2A_YEAST] |
