    HP1α is a chromatin crosslinker that controls nuclear and mitotic chromosome mechanics

    Amy R Strom, Ronald J Biggs ... Andrew D Stephens
    Micromanipulation experiments demonstrate that HP1α strengthens interphase and mitotic chromosome mechanics and maintains nuclear shape by chromatin crosslinking, separate from histone methylation.

    A generic binding pocket for small molecule IKs activators at the extracellular inter-subunit interface of KCNQ1 and KCNE1 channel complexes

    Magnus Chan, Harutyun Sahakyan ... David Fedida
    Characterization of an extra-membrane site in IKs formed by KCNQ1 S1, Pore and S6 domains and the near extracellular region of KCNE1, which forms a binding pocket for channel activators.

    Prolonged partner separation erodes nucleus accumbens transcriptional signatures of pair bonding in male prairie voles

    Julie M Sadino, Xander G Bradeen ... Zoe R Donaldson
    Pair bond induced transcriptional changes in the nucleus accumbens erode after long-term partner separation.

    Deep mutational scanning and machine learning reveal structural and molecular rules governing allosteric hotspots in homologous proteins

    Megan Leander, Zhuang Liu ... Srivatsan Raman
    Deep mutational scanning of homologous proteins shows conservation in allosteric mechanisms but differences in molecular details within the protein family.

    Multiple motors cooperate to establish and maintain acentrosomal spindle bipolarity in C. elegans oocyte meiosis

    Gabriel Cavin-Meza, Michelle M Kwan, Sarah M Wignall
    Rapid depletion of dynein from oocytes yielded new insights into acentrosomal pole organization and also led to the first evidence that the kinesin-5 motor BMK-1 plays a role in microtubule organization during C. elegans meiosis.

    Reverse evolution leads to genotypic incompatibility despite functional and active site convergence

    Miriam Kaltenbach, Colin J Jackson ... Nobuhiko Tokuriki
    Enzyme evolution is reversible on a structural and functional (phenotypic) level, but through a different mutational pathway that leads to genotypic incompatibility with the ancestor.

    Genetic code expansion, click chemistry, and light-activated PI3K reveal details of membrane protein trafficking downstream of receptor tyrosine kinases

    Duk-Su Koh, Anastasiia Stratiievska ... Sharona E Gordon
    The generation of phosphoinositide 3,4,5-trisphosphate causes an increase in the number of TRPV1 ion channels and insulin receptors in the plasma membrane.

    PURA syndrome-causing mutations impair PUR-domain integrity and affect P-body association

    Marcel Proske, Robert Janowski ... Dierk Niessing
    Structural promiscuity in PURA protein, induced by patient mutations, impacts nucleic acid binding, unwinding, and subcellular localization, indicating why so many patients display the full disease spectrum of PURA syndrome.

    Lactate-mediated epigenetic reprogramming regulates formation of human pancreatic cancer-associated fibroblasts

    Tushar D Bhagat, Dagny Von Ahrens ... Amit Verma
    Lactate in pancreatic cancer micro-environment can lead to TET enzyme activation and loss of DNA methylation seen in cancer associated fibroblasts.

    Distinct representation of cue-outcome association by D1 and D2 neurons in the ventral striatum’s olfactory tubercle

    Nuné Martiros, Vikrant Kapoor ... Venkatesh N Murthy
    Real-time imaging of neural activity in behaving mice reveals that the two canonical types of neurons in the olfactory tubercle carry distinct information about learned odor cues, with D1 neurons representing stimulus valence and D2 neurons mainly representing stimulus identity.
