    Optogenetic activation of heterotrimeric G-proteins by LOV2GIVe, a rationally engineered modular protein

    Mikel Garcia-Marcos, Kshitij Parag-Sharma ... Lien T Nguyen
    LOV2GIVe allows to activate Gi proteins non-invasively with innocuous blue light based on a design principle unrelated to light-activated GPCRs (metazoan opsins), thereby expanding the range of potential experimental applications.

    A cross-kingdom conserved ER-phagy receptor maintains endoplasmic reticulum homeostasis during stress

    Madlen Stephani, Lorenzo Picchianti ... Yasin Dagdas
    C53 bridges selective autophagy with ribosome-associated quality control at the endoplasmic reticulum.

    Large domains of heterochromatin direct the formation of short mitotic chromosome loops

    Maximilian H Fitz-James, Pin Tong ... Robin C Allshire
    Large regions of foreign DNA inserted into mammalian chromosomes assemble into H3K9me3-heterochromatin and result in increased condensin loading with organisation into shorter mitotic chromosome loops than endogenous DNA.

    Atg1 kinase in fission yeast is activated by Atg11-mediated dimerization and cis-autophosphorylation

    Zhao-Qian Pan, Guang-Can Shao ... Li-Lin Du
    A mechanistic dissection of how autophagy kinase Atg1 is activated in fission yeast reveals surprising differences from the known Atg1 activation mechanisms previously defined in budding yeast.

    Stress-activated MAPK signaling controls fission yeast actomyosin ring integrity by modulating formin For3 levels

    Elisa Gómez-Gil, Rebeca Martín-García ... Jose Cansado
    Microscopic and biochemical analysis show that the stress-activated MAP kinase pathway targets the formin For3 to modulate actomyosin ring integrity in response to environmental cues.

    Stoichiometric interactions explain spindle dynamics and scaling across 100 million years of nematode evolution

    Reza Farhadifar, Che-Hang Yu ... Daniel J Needleman
    Stoichiometric interactions between microtubules and cortical force-generators set spindle size, position and dynamics, and its scaling with cell size in nematode species.

    An ER translocon for multi-pass membrane protein biogenesis

    Philip T McGilvray, S Andrei Anghel ... Robert J Keenan
    A set of ER-localized membrane proteins whose loss causes developmental diseases in humans, assemble with Sec61 into a translocon that facilitates the biogenesis of hundreds of different multi-pass membrane proteins.

    Multiple Wnts act synergistically to induce Chk1/Grapes expression and mediate G2 arrest in Drosophila tracheoblasts

    Amrutha Kizhedathu, Rose Sebastian Kunnappallil ... Arjun Guha
    Wnts can act synergistically to affect G2 arrest via transcriptional upregulation of a Checkpoint Kinase in the absence of any detectable DNA damage.

    Ubiquitin-interacting motifs of ataxin-3 regulate its polyglutamine toxicity through Hsc70-4-dependent aggregation

    Sean L Johnson, Bedri Ranxhi ... Sokol V Todi
    Pathogenesis in Spinocerebellar Ataxia Type 3 is enhanced by the heat-shock protein family member, Hsc70-4, uncovering new mechanisms of toxicity for this disease and suggesting pleiotropic roles for chaperones.
