    The chromatin remodelers RSC and ISW1 display functional and chromatin-based promoter antagonism

    Timothy J Parnell et al.
    A combination of genetics, expression, genomic localization, and genomic nucleosome profiling demonstrates antagonism between two chromatin remodelers that reveal different mechanisms at different promoter architectures.

    RSC primes the quiescent genome for hypertranscription upon cell-cycle re-entry

    Christine E Cucinotta et al.
    Multiple mechanisms, by which a highly conserved chromatin-remodeling factor RSC facilitates initiation and maintenance of large-scale, rapid gene expression upon exit from quiescent state, have been discovered.

    Specialization of the chromatin remodeler RSC to mobilize partially-unwrapped nucleosomes

    Alisha Schlichter et al.
    A SWI/SNF-family chromatin remodeling subcomplex from yeast is identified (RSC1) that is specialized to slide nucleosomes residing on DNA sequences that confer partial nucleosome unwrapping, with assistance from accessory factors.

    Tsc2 disruption in mesenchymal progenitors results in tumors with vascular anomalies overexpressing Lgals3

    Peter J Klover et al.
    Tsc2 inactivation in mouse mesenchymal progenitors produced tumors with vascular anomalies reminiscent of human angiomyolipomas, and a gene expression signature in Tsc2-deficient tissues which included Lgals3, as a novel potential biomarker for TSC1/2 loss.

    Architecture of the chromatin remodeler RSC and insights into its nucleosome engagement

    Avinash B Patel et al.
    The structure of the yeast RSC complex, a member of the SWI/SNF chromatin remodeling family, determined by cryo-electron microscopy, reveals a conserved structural core and the mode of nucleosome engagement.

    The Rqc2/Tae2 subunit of the ribosome-associated quality control (RQC) complex marks ribosome-stalled nascent polypeptide chains for aggregation

    Ryo Yonashiro et al.
    Rqc2-mediated modification of ribosome-stalled nascent chains with "CAT tails" promotes formation of insoluble aggregates suggesting that proteins can become specifically marked for aggregation.

    Stepwise nucleosome translocation by RSC remodeling complexes

    Bryan T Harada et al.
    Single molecule FRET reveals that the SWI/SNF-family remodeling enzyme RSC translocates nucleosomes along the DNA in steps of ~1-2 base pairs in size.

    Histone H2B ubiquitylation represses gametogenesis by opposing RSC-dependent chromatin remodeling at the ste11 master regulator locus

    Philippe Materne et al.
    Building on previous work (Materne et al., 2015), it is shown that the ubiquitylation of histone H2B represses cell differentiation by opposing chromatin remodeling at the promoter of the master regulator of gametogenesis, ste11

    Control of TSC2-Rheb signaling axis by arginine regulates mTORC1 activity

    Bernadette Carroll et al.
    Signaling pathway mTOR can sense its principal activator amino acid arginine via a different mechanism than that previously described for other amino acids.

    In vitro proteasome processing of neo-splicetopes does not predict their presentation in vivo

    Gerald Willimsky et al.
    Analysis of neo-splicetope-specific T cell responses strongly questions the idea that in vitro proteasome-catalyzed peptide splicing reaction simulates the in vivo situation with the same high fidelity as the in vitro generation of non-spliced epitopes.
