    Directed evolution of the rRNA methylating enzyme Cfr reveals molecular basis of antibiotic resistance

    Kaitlyn Tsai, Vanja Stojković ... Danica Galonić Fujimori
    Directed evolution of the resistance enzyme Cfr under antibiotic selection identifies increased Cfr expression and stability as strategies to boost resistance and reveals that Cfr modification of the ribosome confers resistance by sterically occluding binding of antibiotics.

    NuRD and CAF-1-mediated silencing of the D4Z4 array is modulated by DUX4-induced MBD3L proteins

    Amy E Campbell, Sean C Shadle ... Stephen J Tapscott
    CRISPR/Cas9 engineered locus-specific proteomics leads to the identification of NuRD, CAF-1, and MBD3L2 as regulators of the early embryonic transcription factor DUX4.

    A single-chain and fast-responding light-inducible Cre recombinase as a novel optogenetic switch

    Hélène Duplus-Bottin, Martin Spichty ... Gaël Yvert
    A single protein catalyzes site-specific DNA recombination upon blue-light illumination.

    Missense mutations in CRX homeodomain cause dominant retinopathies through two distinct mechanisms

    Yiqiao Zheng, Chi Sun ... Shiming Chen
    The integrated analysis of multi-omics and functional evidence both in vitro and in knock-in mouse models reveal novel gain-of-function pathogenic mechanisms of dominant CRX HD missense mutations.

    Vernalization-triggered expression of the antisense transcript COOLAIR is mediated by CBF genes

    Myeongjune Jeon, Goowon Jeong ... Ilha Lee
    CBFs, the central regulators of low-temperature signaling, have a function to directly activate the expression of COOLAIR, an antisense RNA of FLC, during vernalization process, but COOLAIR is not required for the vernalization response.

    Molecular basis for catabolism of the abundant metabolite trans-4-hydroxy-L-proline by a microbial glycyl radical enzyme

    Lindsey RF Backman, Yolanda Y Huang ... Catherine L Drennan
    The common post-translational modification trans-4-hydroxy-L-proline is reversed by gut microbes with the help of hydroxyproline dehydratase (HypD), an enzyme that performs a radical chemical mechanism.

    SRF-deficient astrocytes provide neuroprotection in mouse models of excitotoxicity and neurodegeneration

    Surya Chandra Rao Thumu, Monika Jain ... Narendrakumar Ramanan
    Serum response factor (SRF) deficient reactive astrocytes are neuroprotective in the mammalian brain.
