    Imaging and energetics of single SSB-ssDNA molecules reveal intramolecular condensation and insight into RecOR function

    Jason C Bell, Bian Liu, Stephen C Kowalczykowski
    Individual SSB-ssDNA complexes undergo reversible condensation and de-condensation that is modulated by RecOR during recombination.

    Rev7 and 53BP1/Crb2 prevent RecQ helicase-dependent hyper-resection of DNA double-strand breaks

    Bryan A Leland, Angela C Chen ... Megan C King
    A single-cell assay reveals that the genetic rewiring that underlies PARP inhibitor resistance drives altered DNA double-strand break end resection pathway choice.

    Mapping replication dynamics in Trypanosoma brucei reveals a link with telomere transcription and antigenic variation

    Rebecca Devlin, Catarina A Marques ... Richard McCulloch
    Mapping DNA replication timing, allied to genetic analysis of a RecQ repair helicase, reveals that antigenic variation in the African trypanosome may be initiated by locus-specific, replication-derived sequence instability.

    Reconstitution of dynein transport to the microtubule plus end by kinesin

    Anthony J Roberts, Brian S Goodman, Samara L Reck-Peterson
    In vitro reconstitution reveals how a system of molecules works together to transport the motor protein dynein to the start of its track.

    Cytoplasmic dynein-1 cargo diversity is mediated by the combinatorial assembly of FTS–Hook–FHIP complexes

    Jenna R Christensen, Agnieszka A Kendrick ... Samara L Reck-Peterson
    The combinatorial assembly of different adaptor complexes is a mechanism that dynein uses to interact with multiple cargos.

    Lis1 regulates dynein by sterically blocking its mechanochemical cycle

    Katerina Toropova, Sirui Zou ... Andres E Leschziner
    Structural and functional studies reveal how a ubiquitous regulator of dynein keeps the microtubule-based motor in a persistent track-bound state.

    Structures of RecBCD in complex with phage-encoded inhibitor proteins reveal distinctive strategies for evasion of a bacterial immunity hub

    Martin Wilkinson, Oliver J Wilkinson ... Mark S Dillingham
    New cryoEM structures reveal how small bacteriophage proteins suppress bacterial immunity.

    Tip cell-specific requirement for an atypical Gpr124- and Reck-dependent Wnt/β-catenin pathway during brain angiogenesis

    Benoit Vanhollebeke, Oliver A Stone ... Didier YR Stainier
    The membrane proteins Reck and Gpr124 are integral components of a novel Wnt7a/Wnt7b-specific signaling complex, and there is a distinctive requirement for Wnt/β-catenin signaling in tip cells during angiogenesis in the central nervous system.

    Human DNA2 possesses a cryptic DNA unwinding activity that functionally integrates with BLM or WRN helicases

    Cosimo Pinto, Kristina Kasaciunaite ... Petr Cejka
    The nuclease of hDNA2 limits its processive DNA unwinding capacity; the helicase function becomes stimulatory when hDNA2 is in complex with BLM or WRN helicase to degrade dsDNA.

    Spatial and temporal organization of RecA in the Escherichia coli DNA-damage response

    Harshad Ghodke, Bishnu P Paudel ... Antoine M van Oijen
    Phase separated DNA-free stored forms of RecA dissolve in response to DNA damage to make RecA available for repair and recombination reactions as part of the bacterial (Escherichia coli) SOS response.
