Abstract

In contrast to mRNAs, which are templates for translating proteins, non-protein coding (npc) RNAs (also known as 'non-coding' RNA, ncRNA), exhibit various functions in different compartments and developmental stages of the cell. Small nucleolar RNAs (snoRNAs), one of the largest classes of npcRNAs, guide post-transcriptional modifications of other RNAs that are crucial for appropriate RNA folding as well as for RNA-RNA and RNA-protein interactions. Although snoRNA genes comprise a significant fraction of the eutherian genome, identifying and characterizing large numbers of them is not sufficiently accessible by classical computer searches alone. Furthermore, most previous investigations of snoRNAs yielded only limited indications of their evolution. Using data obtained by a combination of high-throughput cDNA library screening and computational search strategies based on a modified DNAMAN program, we characterized 151 npcRNAs, and in particular 121 snoRNAs, from Caenorhabditis elegans and extensively compared them with those in the related, Caenorhabditis briggsae. Detailed comparisons of paralog snoRNAs in the two nematodes revealed, in addition to trans-duplication, a novel, cis-duplication distribution strategy with insertions near to the original loci. Some snoRNAs coevolved with their modification target sites, demonstrating the close interaction of complementary regions. Some target sites modified by snoRNAs were changed, added or lost, documenting a high degree of evolutionary plasticity of npcRNAs.

  • The presence of structural requirements important in snoRNA function and evidence of expression are consistent with snoRTE elements being functional in platypus.

    “The presence of both the structural requirements known to be important in snoRNA function 24 and evidence of their expression are consistent with these snoRTE elements being functional in the platypus.”

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.
