    The PCNA unloader Elg1 promotes recombination at collapsed replication forks in fission yeast

    Sanjeeta Tamang et al.
    Unloading the polymerase sliding clamp PCNA from DNA by Elg1 promotes recombination at the RTS1 replication fork barrier by limiting Fbh1 and Srs2 activity.

    Cell-autonomous regulation of epithelial cell quiescence by calcium channel Trpv6

    Yi Xin et al.
    Genetics, in vivo imaging, and unbiased chemical biology screens reveal that Trpv6 functions as a cellular quiescence regulator and delineates a Trpv6-mediated Ca2+ signaling pathway maintaining the quiescent state.

    An explanation for origin unwinding in eukaryotes

    Lance D Langston, Michael E O'Donnell
    CMG helicase translocates with force while encircling duplex DNA, enabling two opposing CMG complexes at an origin to melt the duplex and switch to encircling separate single strands.

    Astrocyte morphogenesis is dependent on BDNF signaling via astrocytic TrkB.T1

    Leanne M Holt et al.
    Brain-derived neurotrophic factor (BDNF)/TrkB.T1 signaling contributes to astrocyte morphological maturation, with implications for neuronal synaptogenesis and function and astrocyte functional maturation.

    E. coli TraR allosterically regulates transcription initiation by altering RNA polymerase conformation

    James Chen et al.
    Cryo-electron microscopy structures, combined with biochemical experiments, show how the E. coli F element-encoded TraR protein regulates transcription initiation by altering RNA polymerase conformation and conformational heterogeneity.
