The carboxy-terminal domain (CTD) of RNA polymerase (Pol) II is composed of a repetition of YSPTSPS heptads and functions as a loading platform for protein complexes that regulate transcription, splicing, and maturation of RNAs. Here, we studied mammalian CTD mutants to analyze the function of tyrosine1 residues in the transcription cycle. Mutation of 3/4 of the tyrosine residues (YFFF mutant) resulted...
The explosion of high throughput sequencing technologies marked a turn in our way of understanding the complexity and diversity of the transcriptome, including noncoding transcription dependent on RNA polymerase II. Many new ncRNA populations were described in recent years, including for example TSS RNAs, lincRNAs, eRNAs, PROMPTS and several others. Besides the advances in the average depth coverage...
Type I interferons (IFNs) are central to antiviral defense, but how they orchestrate immune cell function is incompletely understood. We determined that IFNs produced during murine cytomegalovirus (MCMV) infection differentially affect dendritic cells (DCs) and natural killer (NK) cells. IFNs induce cell-intrinsic responses in DCs, activating antiproliferative, antiviral, and lymphocyte-activating...
