Biogenesis of small nucleolar ribonucleoproteins

Filipowicz, Witold, Pogačić, Vanda·2002·Current Opinion in Cell Biology

Abstract

Eukaryotic cells contain a very complex population of small nucleolar RNAs. They function, as small nucleolar ribonucleoproteins, in pre-ribosomal RNA processing reactions, and also guide methylation and pseudouridylation of ribosomal RNA, spliceosomal small nuclear RNAs, and possibly other cellular RNAs. Synthesis of small nucleolar RNAs frequently follows unusual strategies. Some newly discovered brain-specific small nucleolar RNAs of unknown function are encoded in introns of tandemly repeated units, expression of which is paternally imprinted. Recent studies of the protein components and factors participating in small nucleolar ribonucleoprotein assembly have revealed interesting connections with other classes of cellular ribonucleoproteins such as spliceosomal small nuclear ribonucleoproteins and telomerase. Cajal bodies emerge as nuclear structures important for the biogenesis and function of small nucleolar ribonucleoproteins.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
