Web14 Apr 2024 · Abstract. MicroRNAs are small single-stranded non-coding RNAs that regulate gene expression post-transcriptionally, by targeting the 3‘-untranslated region (3’-UTR) of mRNAs. The regulation of microRNAs at the transcriptional level is well-studied, however, how their activity is regulated remains largely elusive. The family of Akt serine/threonine … Web23 Jan 2014 · The phosphorylation of IWS1 attracts SetD2 to the Spt6/IWS1/Aly complex in the CTD of RNA Pol II. SetD2 in the complex trimethylates histone H3 at K36 during transcriptional elongation. MRG15 and its partner PTB bind histone H3K36me3. Binding of PTB to the IIIb exon promotes exclusion of this exon from the spliced transcript.
