    Molecular basis for substrate specificity of the Phactr1/PP1 phosphatase holoenzyme

    Roman O Fedoryshchak, Magdalena Přechová ... Richard Treisman
    Interaction of cofactor Phactr1 with PP1 creates a composite substrate-binding surface that defines the sequence specificity of the Phactr1/PP1 holoenzyme.

    Differential temporal dynamics during visual imagery and perception

    Nadine Dijkstra, Pim Mostert ... Marcel AJ van Gerven
    In contrast to perception, during visual imagery, there are no clear time-locked processing stages and imagery specifically overlaps with perceptual processing around 160 ms after stimulus onset and from 300 ms onwards.

    Synapse maintenance is impacted by ATAT-2 tubulin acetyltransferase activity and the RPM-1 signaling hub

    Melissa A Borgen, Andrew C Giles ... Brock Grill
    Genetic, developmental and pharmacological analysis in Caenorhabditis elegans demonstrate that ATAT-2 tubulin acetyltransferase activity regulates synapse maintenance by acting within the RPM-1 signaling network, but independent of the DLK-1 MAP3K.

    PPI-hotspotID for detecting protein–protein interaction hot spots from the free protein structure

    Yao Chi Chen, Karen Sargsyan ... Carmay Lim
    PPI-hotspotID, trained using an automated machine-learning framework, AutoGluon, on the largest PPI-hot spot dataset to date, detects hot spots beyond protein–protein interfaces, uncovering druggable interactions to aid design of PPI-modulating therapeutics.

    NHR-14 loss of function couples intestinal iron uptake with innate immunity in C. elegans through PQM-1 signaling

    Malini Rajan, Cole P Anderson ... Elizabeth A Leibold
    Nuclear receptor NHR-14 regulates the subcellular localization of the zinc transcription factor PQM-1 to coordinate innate immunity with iron sequestration during pathogen infection in C. elegans..

    The genomes of polyextremophilic cyanidiales contain 1% horizontally transferred genes with diverse adaptive functions

    Alessandro W Rossoni, Dana C Price ... Andreas PM Weber
    Horizontal gene transfer (HGT) analysis in polyextremophile red algae (Cyanidiales) provides explanations for the nonexistence of cumulative effects and eukaryotic pangenomes, and highlights differences between HGT and native genes.

    Shank is a dose-dependent regulator of Cav1 calcium current and CREB target expression

    Edward Pym, Nikhil Sasidharan ... Joshua M Kaplan
    Changes in Shank gene dosage alter voltage-activated calcium current and calcium-activated gene expression in a manner that parallels the effects of human Shank copy number variation on psychiatric disease risk.

    Aurkb/PP1-mediated resetting of Oct4 during the cell cycle determines the identity of embryonic stem cells

    Jihoon Shin, Tae Wan Kim ... Hong-Duk Youn
    The regulation of the core transcription factor Oct4 by the Aurkb-PP1 axis links the cell cycle to pluripotency programs in embryonic stem cells.

    Molecular determinants of the Ska-Ndc80 interaction and their influence on microtubule tracking and force-coupling

    Pim J Huis in 't Veld, Vladimir A Volkov ... Marileen Dogterom
    Binding of two macromolecular complexes allows kinetochores to capture force produced by the depolymerising ends of microtubules, allowing chromosomes to be transmitted from a mother cell to its two daughters.

    Multivalency of NDC80 in the outer kinetochore is essential to track shortening microtubules and generate forces

    Vladimir A Volkov, Pim J Huis in 't Veld ... Andrea Musacchio
    Multiple NDC80 complexes in the outer kinetochore cooperate to bind the ends of depolymerizing microtubules and harness their power stroke.
