    Functional characteristics and computational model of abundant hyperactive loci in the human genome

    Sanjarbek Hudaiberdiev, Ivan Ovcharenko
    Large-scale multi-omics analysis of genomic high-occupancy target regions in humans suggests involvement of large transcriptional condensates.

    Heat Shock Factor 1 forms nuclear condensates and restructures the yeast genome before activating target genes

    Linda S Rubio, Suman Mohajan, David S Gross
    In response to ethanol stress, the yeast transcription factor Hsf1 forms nuclear condensates and drives the coalescence of target genes prior to their transcriptional activation while in response to thermal stress these three phenomena are tightly coordinated.

    Transcription factor condensates, 3D clustering, and gene expression enhancement of the MET regulon

    James Lee, Leman Simpson ... Lu Bai
    The condensates of activator Met4 are associated with 3D clustering of the MET regulon and its enhanced expression.

    Endoplasmic reticulum tubules limit the size of misfolded protein condensates

    Smriti Parashar, Ravi Chidambaram ... Susan Ferro-Novick
    The endoplasmic reticulum (ER) uses ER tubules and specific ER autophagy machinery to prevent toxic, dominant-interfering, disease-causing, mutant proteins from entering the secretory pathway.

    How subtle changes in 3D structure can create large changes in transcription

    Jordan Yupeng Xiao, Antonina Hafner, Alistair N Boettiger
    Promoter futile cycles can explain how subtle differences in genome folding sometimes generate large difference in gene expression.

    Principles of RNA recruitment to viral ribonucleoprotein condensates in a segmented dsRNA virus

    Sebastian Strauss, Julia Acker ... Ralf Jungmann
    Spatial transcriptomics analysis of rotavirus replication factories reveals principles of viral transcript partitioning and RNA stoichiometry in these granules.

    HP1 proteins compact DNA into mechanically and positionally stable phase separated domains

    Madeline M Keenen, David Brown ... Sy Redding
    Heterochromatin proteins compartmentalize DNA into compact structures resistant to mechanical disruption but susceptible to competitive dissolution.

    In vivo reconstitution finds multivalent RNA–RNA interactions as drivers of mesh-like condensates

    Weirui Ma, Gang Zhen ... Christine Mayr
    Binding of a multivalent RNA-binding protein to mRNAs that are able to form pervasive RNA–RNA interactions induces formation of mesh-like condensates, whereas binding of mostly structured mRNAs induces sphere-like condensates.
