    MutSα maintains the mismatch repair capability by inhibiting PCNA unloading

    Yoshitaka Kawasoe, Toshiki Tsurimoto ... Tatsuro S Takahashi
    Biochemical analysis in Xenopus egg extracts reveals that the MutSα mismatch sensor retains the DNA-bound replication clamp to maintain a post-replicative temporal window permissive to strand-specific repair of mismatches.

    Thousands of novel translated open reading frames in humans inferred by ribosome footprint profiling

    Anil Raj, Sidney H Wang ... Jonathan K Pritchard
    Over 7,000 novel translated sequences have been identified from human cells, including several hundred in annotated noncoding RNA, pseudogenes and de novo assembled transcripts.

    Multi-step coordination of telomerase recruitment in fission yeast through two coupled telomere-telomerase interfaces

    Xichan Hu, Jinqiang Liu ... Feng Qiao
    A telomerase recruitment mechanism delivers cell cycle information to the telomere-telomerase interface to ensure timely telomerase engagement at the telomere.

    RNA Polymerase II cluster dynamics predict mRNA output in living cells

    Won-Ki Cho, Namrata Jayanth ... Ibrahim I Cisse
    Quantitative super resolution imaging, in live mammalian cells, reveals a direct relationship between protein clustering dynamics and the number of mRNA transcribed at an endogenous gene locus.

    Developmental programming modulates olfactory behavior in C. elegans via endogenous RNAi pathways

    Jennie R Sims, Maria C Ow ... Sarah E Hall
    The OSM-9 TRPV channel is differentially regulated due to developmental programming via modulation by TGF-β signaling, endogenous RNAi and chromatin remodeling pathways.

    Activation of GCN2 kinase by ribosome stalling links translation elongation with translation initiation

    Ryuta Ishimura, Gabor Nagy ... Susan L Ackerman
    Activation of the integrated stress response by stalled translation elongation complexes attenuates neurodegeneration, and demonstrates a protective link between a decrease in the rate of translation initiation and defects in translation elongation.

    PHF13 is a molecular reader and transcriptional co-regulator of H3K4me2/3

    Ho-Ryun Chung, Chao Xu ... Sarah Kinkley
    PHF13 interacts with transcriptional complexes containing RNA polymerase II to recruit/stabilize them at H3K4me2/3 containing active or bivalent promoters.

    Nucleosome disassembly during human non-homologous end joining followed by concerted HIRA- and CAF-1-dependent reassembly

    Xuan Li, Jessica K Tyler
    The human genome is unpackaged to allow DNA breaks to be joined back together, and then repackaged into chromosomes afterwards.

    Compaction and segregation of sister chromatids via active loop extrusion

    Anton Goloborodko, Maxim V Imakaev ... Leonid Mirny
    Loop extrusion can robustly compact, segregate and disentangle mammalian chromosomes, suggesting it is a universal mechanism of genome folding during cell division.
