Transcriptional suppression of ribosomal DNA with phase

Our findings suggest a mechanism of rRNA transcription suppression via phase separation of intranucleolar molecules governed by Pol I.The nucleolus is a nuclear body with multiphase liquidThe liquid nucleome phase transitions in the nucleus at Phase separation-based transcriptional condensates provide an explanation for the observation that a single enhancer can simultaneously co-activate multiple distinct promoters (Fukaya et al.,2016),as well as explaining the process of transvection,in which an enhancer on one chromosome can initiate transcription at a promoter on a different chromosome (Lim et al.,2018).TranscriptionalTaf14 recognizes a common motif in transcriptional Taf14 recognizes a common motif in transcriptional machineries and facilitates their clustering by phase separation Saccharomyces cerevisiae TBP associated factor 14 (Taf14) is a well-studied transcriptional regulator that controls diverse physiological processes and that physically interacts with at least seven nuclear complexes in yeast.

Phase Separation and Transcription Regulation Are Super

Assembly and transfer of transcription complexes is facilitated by phase separation,which contributes to concentrating all activities at SEs and LCRs and may also facilitate the recruitment of target genes to the phase separated domains.66 Because of the multiple HSs associated with SEs and LCRs,the transient interactions allow a large number of elongation competent transcription complexes to be transferred toNuclear microenvironment in cancer Control through liquid Jun 28,2020 A Phase Separation Model for Transcriptional Control#0183;Liquidliquid phase separation is also involved in higherorder chromatin structure.Superresolution imaging in live cells demonstrated that chromatin represents dynamic and liquidlike properties in the nucleus,rather than static and physically constrained solidphase structures 15 (Figure 2C).This observation inspired us to Modes of phase separation affecting chromatin regulation Oct 16,2019 A Phase Separation Model for Transcriptional Control#0183;Of the two models that have been proposed for phase-separated entities,one largely depends on chromatinprotein interactions and the other on multivalent proteinprotein and/or proteinRNA ones.Each has its own characteristics,but both would be able to,at least in part,explain chromatin and transcriptional organization.
