    Hidden long-range memories of growth and cycle speed correlate cell cycles in lineage trees

    Erika E Kuchen et al.
    The combination of statistical inference and perturbation experiments reveals that trans-generational inheritance of cell size and cell-cycle speed, coupled through a minimum-size checkpoint, shapes paradoxical cell-cycle correlations in lineage trees.

    In vivo single-cell lineage tracing in zebrafish using high-resolution infrared laser-mediated gene induction microscopy

    Sicong He et al.
    Infrared laser-mediated gene induction microscopy enables precise single-cell labeling in various tissues of zebrafish, and in vivo visualized single-cell lineage tracing reveals the lineage heterogeneity in hematopoietic endothelial cells.

    Cryo-EM structures demonstrate human IMPDH2 filament assembly tunes allosteric regulation

    Matthew C Johnson, Justin M Kollman
    Assembly of the human enzyme inosine monophosphate dehydrogenase 2 into filaments promotes substrate-dependent resistance to feedback inhibition by downstream products, promoting increased flux during proliferative states.

    Human Neocortical Neurosolver (HNN), a new software tool for interpreting the cellular and network origin of human MEG/EEG data

    Samuel A Neymotin et al.
    Human Neocortical Neurosolver is a new user-friendly software tool for researchers to develop and test hypotheses on cellular/circuit origins of human MEG/EEG signals using a biophysical model.

    Structure of the AAA protein Msp1 reveals mechanism of mislocalized membrane protein extraction

    Lan Wang et al.
    Msp1 recruits substrates at the open seam of the spiral oligomer and extracts them with functionally adapted elements.

    Structure of the human BBSome core complex

    Björn Udo Klink et al.
    The structure of the human BBSome explains how the subunits interact with each other and how disease-causing mutations hamper this interaction.

    Structure and activation mechanism of the BBSome membrane protein trafficking complex

    Sandeep K Singh et al.
    Two cryo-EM structures of the mammalian BBSome show how the BBSome is recruited to membranes and activated by the GTPase ARL6 prior to binding transmembrane proteins.

    Intraflagellar Transport: Moving proteins along in the cilium

    Narcis Adrian Petriman, Esben Lorentzen
    The structures of the bovine and human BBSome reveal that a conformational change is required to recruit the complex to the ciliary membrane.

    The speed of GTP hydrolysis determines GTP cap size and controls microtubule stability

    Johanna Roostalu et al.
    GTPase-deficient microtubules are hyper-stable and have longer EB binding regions, demonstrating that EBs bind the GTP cap.

    Nodal β spectrins are required to maintain Na+ channel clustering and axon integrity

    Cheng-Hsin Liu et al.
    A combination of sensory-neuron specific conditional knockout mice reveal nodal beta spectrins are required to maintain, but not assemble, nodes of Ranvier.
