Zcchc11-dependent uridylation of microRNA directs cytokine expression
Open accessAbstract
Mounting an effective host immune response without incurring inflammatory injury requires the precise regulation of cytokine expression. To achieve this, cytokine mRNAs are post-transcriptionally regulated by diverse RNA-binding proteins and microRNAs (miRNAs) targeting their 3′ untranslated regions (UTRs). Zcchc11 (zinc-finger, CCHC domain-containing protein 11) contains RNA-interacting motifs, and has been implicated in signalling pathways involved in cytokine expression. The nature of the Zcchc11 protein and how it influences cytokine expression are unknown. Here we show that Zcchc11 directs cytokine expression by uridylating cytokine-targeting miRNAs. Zcchc11 is a ribonucleotidyltransferase with a preference for uridine and is essential for maintaining the poly(A) tail length and stability of transcripts for interleukin-6 (IL-6) and other specific cytokines. The miR-26 family of miRNAs targets IL-6, and the addition of terminal uridines to the miR-26 3′ end abrogates IL-6 repression. Whereas 78% of miR-26a sequences in control cells contained 1–3 uridines on their 3′ ends, less than 0.1% did so in Zcchc11-knockdown cells. Thus, Zcchc11 fine tunes IL-6 production by uridylating miR-26a, which we propose is an enzymatic modification of the terminal nucleotide sequence of mature miRNA as a means to regulate gene expression.

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.
