An Intrinsically Disordered Region Controlling Condensation of a Circadian Clock Component and Rhythmic Transcription in the Liver [ChIP-seq]

Project description:Circadian gene transcription is fundamental to metabolic physiology. Here we report that the nuclear receptor REV-ERBalpha, a repressive component of the molecular clock, forms circadian condensates in the nuclei of mouse Liver. These condensates are dictated by an intrinsically disordered region (IDR) located in the protein’s hinge region which specifically concentrates nuclear receptor corepressor 1 (NCOR1) at the genome. IDR deletion diminishes the recruitment of NCOR1 and disrupts rhythmic gene transcription in vivo. REV-ERBalpha condensates are located at high-order transcriptional repressive hubs in the Liver genome that are highly correlated with circadian gene repression. Deletion of the IDR disrupts transcriptional repressive hubs and diminishes silencing of target genes by REV-ERBalpha. This work demonstrates physiological circadian protein condensates containing REV-ERBalpha whose IDR is required for hub formation and the control of rhythmic gene expression.

Recruitment of mRNAs to P granules by gelation with intrinsically-disordered proteins (iCLIP results)

Project description:RNA granules are cellular condensates that contain RNAs and proteins. The mechanism that drive the recruitment of many mRNAs to RNA granules are not fully understood. Here we characterize the assembly and transcriptome of the germ (P) granules of C. elegans. We find that mRNAs are recruited into P granules by condensation with the intrinsically-disordered protein MEG-3. MEG-3 binds ~500 mRNAs in C. elegans embryos in a sequence-independent manner that favors mRNAs with low ribosome coverage. Translational stress causes additional mRNAs to localize to P granules and translational activation correlates with P granule exit for two mRNAs coding for germ cell fate regulators. MEG-3/RNA condensates assembled in vitro are gel-like and trap mRNAs in a non-dynamic state. Our observations reveal similarities between P granules and stress granules and identify gelation with intrinsically-disordered proteins as a sequence-independent mechanism to enrich low-translation mRNAs in RNA granules

Proteomic and bioinformatic analysis of the nuclear intrinsically disordered proteome

Project description:Intrinsically disordered proteins (IDPs) are biologically active molecules which are involved in many cellular functions although they do not possess a defined three-dimensional structure. They are mostly signalling and regulatory proteins. This study is the first large-scale proteomic analysis of the nuclear IDPs. We experimentally showed that IDPs are overrepresented in the nucleus in comparison to the whole cell. The analysis in terms of molecular function indicated that nuclear intrinsically disordered proteome (IDP-ome) is enriched in proteins involved in transcription regulation and especially in transcription factors.
