    Genome-wide mapping of native co-localized G4s and R-loops in living cells

    Ting Liu, Xing Shen ... Zhihong Xue
    The newly developed antibody-free techniques, HepG4-seq for G-quadruplexes and HBD-seq for R-loops, robustly reveal the comprehensive maps of native G-quadruplexes and R-loops, as well as their roles in transcriptional regulation.

    CRISPR-Cas12a exploits R-loop asymmetry to form double-strand breaks

    Joshua C Cofsky, Deepti Karandur ... Jennifer A Doudna
    The DNA flanks on either side of an R-loop differ in stability, and CRISPR-Cas12 enzymes form double-strand breaks by targeting the more unstable flank with their single DNase active site.

    Epigenetic reprogramming by TET enzymes impacts co-transcriptional R-loops

    João C Sabino, Madalena R de Almeida ... Sérgio Fernandes de Almeida
    The deposition of 5-hydroxymethylcytosine epigenetic marks in active genes promotes the annealing of the nascent RNA to the template DNA strand, forming an R-loop.

    The Smc5/6 complex counteracts R-loop formation at highly transcribed genes in cooperation with RNase H2

    Shamayita Roy, Hemanta Adhikary ... Damien D'Amours
    Genetic analyses in budding yeast coupled with biochemical assays have revealed an unexpected role for the Smc5/6 complex in cellular pathways responsible for the prevention of RNA formation in genomic DNA.

    The interplay of RNA:DNA hybrid structure and G-quadruplexes determines the outcome of R-loop-replisome collisions

    Charanya Kumar, Sahil Batra ... Dirk Remus
    Reconstitution of orientation-specific R-loop-replisome collisions with purified proteins reveals the differential impact of R-loop-associated RNA:DNA hybrids and G-quadruplexes on replication fork progression.

    A recombinant BBSome core complex and how it interacts with ciliary cargo

    Björn Udo Klink, Eldar Zent ... Alfred Wittinghofer
    Six BBS proteins form a core BBSome transport vehicle, which is sufficient for recognizing membrane proteins for transport into the ciliary compartment.

    Structural insights into the molecular mechanisms of myasthenia gravis and their therapeutic implications

    Kaori Noridomi, Go Watanabe ... Lin Chen
    Autoantibodies from myasthenia gravis patients bind a common core region on the nicotinic acetylcholine receptor through a largely conserved mechanism.

    Integrative dynamic structural biology unveils conformers essential for the oligomerization of a large GTPase

    Thomas-O Peulen, Carola S Hengstenberg ... Christian Herrmann
    Multimodal spectroscopy (smFRET, EPR, SAXS, and SANS) and integrative structural modeling reveal large-scale domain rearrangements in human guanylate binding protein 1 (hGBP1) that are driving forces for the formation of oligomers that enable its biological function in innate immune defense.

    Molecular basis of the PIP2-dependent regulation of CaV2.2 channel and its modulation by CaV β subunits

    Cheon-Gyu Park, Wookyung Yu, Byung-Chang Suh
    The anchoring properties of CaV β2 subunits to the plasma membrane determine the biophysical states of CaV2.2 channels by regulating PIP2 coupling to the nonspecific phospholipid-binding site in the I–II loop.
