Abstract

Summary How genes are regulated to produce the correct assortment of proteins for every cell type is a fundamental question in biology. For many genes, regulation begins at the DNA level using promoter sequences to control transcription. Regulation can also occur after transcription using sequences in the 3’ untranslated region (UTR) of the mRNA to affect mRNA stability and/or translation. Using a transgenic assay, we have compared the contribution of promoters and 3’UTRs to gene regulation in the C. elegans germline. We find that for most genes tested, 3’ UTRs were sufficient for regulation. With the exception of promoters activated during spermatogenesis, promoters were permissive for expression in all germ cell types (from undifferentiated progenitors to mature oocytes and sperm) and showed no cell-type specificity. In progenitors, 3’ UTRs inhibit the production of meiotic and oocyte proteins by post-transcriptional mechanisms involving two classes of RNA-binding proteins (PUF and KH domain proteins). Our findings indicate that many genes rely primarily on 3’UTRs, not promoters, for regulation during germline development.

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.
