Identification of putative reader proteins of 5-methylcytosine and its derivatives in Caenorhabditis elegans RNA

Open access

Preprint — published as 10.12688/wellcomeopenres.17893.1

Abstract

Methylation of carbon-5 of cytosines (m 5 C) is a post-transcriptional nucleotide modification of RNA with widespread distribution across organisms. m 5 C has been shown to participate in mRNA transport and maintain mRNA stability through its recognition by the reader proteins ALYREF and YBX1, respectively. We recently showed that m 5 C is required for Caenorhabditis elegans development and fertility under heat stress. To contribute to the understanding of how m 5 C and its oxidative derivatives mediate their functions, we developed RNA baits bearing modified cytosines in diverse structural contexts to pulldown potential readers in C. elegans . Our mass spectrometry analyses reveal unique binding proteins for each of the modifications. We validate our dataset by demonstrating that the nematode ALYREF homologues ALY-1 and ALY-2 preferentially bind m 5 C in vitro . The dataset presented here serves as an important scientific resource that will support the discovery of new functions of m 5 C and its derivatives.

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.
