    Role of BRCA2 DNA-binding and C-terminal domain in its mobility and conformation in DNA repair

    Maarten W Paul, Arshdeep Sidhu ... Claire Wyman
    Highly conserved C-terminal domains of the tumor suppressor BRCA2 are not essential for accumulation at damaged DNA but affect conformation and cell survival, implying roles beyond delivering strand-exchange protein RAD51.

    High-throughput mapping of single-neuron projection and molecular features by retrograde barcoded labeling

    Peibo Xu, Jian Peng ... Yuejun Chen
    A multiplexed retrograde virus tracing method captures single-neuron projectome and transcriptome simultaneously.

    Pharmacological hallmarks of allostery at the M4 muscarinic receptor elucidated through structure and dynamics

    Ziva Vuckovic, Jinan Wang ... David M Thal
    Structural biology studies reveal the importance of protein dynamics on understanding molecular mechanisms underlying allosteric modulation of G protein-coupled receptors (GPCR) that offer insights into future GPCR research and drug discovery.

    Divisive suppression explains high-precision firing and contrast adaptation in retinal ganglion cells

    Yuwei Cui, Yanbin V Wang ... Daniel A Butts
    The convergence of two visual pathways at the level of retinal bipolar cells accounts for key features of ganglion cell responses.

    Cell and circuit origins of fast network oscillations in the mammalian main olfactory bulb

    Shawn D Burton, Nathaniel N Urban
    Fast network oscillations in the mammalian main olfactory bulb emerge from the dense synchronization of gamma-frequency firing among resonant tufted cells.

    Mechanisms underlying microglial colonization of developing neural retina in zebrafish

    Nishtha Ranawat, Ichiro Masai
    Genetic and imaging analysis reveal that microglial precursors use ocular blood vessels as a pathway to enter the optic cup and subsequently infiltrate the retina preferentially through the neurogenic region.

    The transcription factor Xrp1 orchestrates both reduced translation and cell competition upon defective ribosome assembly or function

    Marianthi Kiparaki, Chaitali Khan ... Nicholas E Baker
    Ribosomal protein mutations, mutations that affect ribosomal RNA synthesis, or function of the mature ribosome, trigger a transcriptional response mediated by Xrp1 expression which reduces cellular translation via eIF2-alpha phosphorylation and renders cells liable to competition with wild-type neighbors.

    Mechanisms that allow cortical preparatory activity without inappropriate movement

    Timothy R Darlington, Stephen G Lisberger
    The use of preparatory activity in the smooth eye movement region of the frontal eye fields as a visual-motor gain signal allows preparation to progress without inappropriate movement.

    Mitochondrial protein import clogging as a mechanism of disease

    Liam P Coyne, Xiaowen Wang ... Xin Jie Chen
    Missense mutations in the nuclear-encoded adenine nucleotide translocase 1 (Ant1) cause the protein to clog the mitochondrial protein import pathway, to severely inhibit cell growth in yeast, and to cause neurodegeneration and myopathy in mice that phenocopy ANT1-induced human disease.

    STRIPAK directs PP2A activity toward MAP4K4 to promote oncogenic transformation of human cells

    Jong Wook Kim, Christian Berrios ... William C Hahn
    ST recruitment of STRIPAK facilitates PP2A-mediated dephosphorylation of MAP4K4 and induces cell transformation highlighting that STRIPAK complex plays a key role in defining PP2A specificity and activity.
