CC -!- FUNCTION: Non-catalytic component of the RNA exosome complex which has
CC 3'->5' exoribonuclease activity and participates in a multitude of
CC cellular RNA processing and degradation events. In the nucleus, the RNA
CC exosome complex is involved in proper maturation of stable RNA species
CC such as rRNA, snRNA and snoRNA, in the elimination of RNA processing
CC by-products and non-coding 'pervasive' transcripts, such as antisense
CC RNA species and cryptic unstable transcripts (CUTs), and of mRNAs with
CC processing defects, thereby limiting or excluding their export to the
CC cytoplasm. In the cytoplasm, the RNA exosome complex is involved in
CC general mRNA turnover and in RNA surveillance pathways, preventing
CC translation of aberrant mRNAs. The catalytic inactive RNA exosome core
CC complex of 9 subunits (Exo-9) is proposed to play a pivotal role in the
CC binding and presentation of RNA for ribonucleolysis, and to serve as a
CC scaffold for the association with catalytic subunits and accessory
CC proteins or complexes. ski6 is part of the hexameric ring of RNase PH
CC domain-containing subunits proposed to form a central channel which
CC threads RNA substrates for degradation (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Component of the RNA exosome complex. Specifically part of the
CC catalytically inactive RNA exosome core (Exo-9) complex which
CC associates with catalytic subunits dis3 and rrp6 in cytoplasmic- and
CC nuclear-specific RNA exosome complex forms. Exo-9 is formed by a
CC hexameric ring of RNase PH domain-containing subunits and peripheral S1
CC domain-containing components csl4, rrp4 and rrp40 located on the top of
CC the ring structure (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:16823372}. Nucleus,
CC nucleolus {ECO:0000269|PubMed:16823372}.
CC -!- SIMILARITY: Belongs to the RNase PH family. {ECO:0000305}.
