    Molecular basis of the PIP2-dependent regulation of CaV2.2 channel and its modulation by CaV β subunits

    Cheon-Gyu Park, Wookyung Yu, Byung-Chang Suh
    The anchoring properties of CaV β2 subunits to the plasma membrane determine the biophysical states of CaV2.2 channels by regulating PIP2 coupling to the nonspecific phospholipid-binding site in the I–II loop.

    Self-assembling manifolds in single-cell RNA sequencing data

    Alexander J Tarashansky, Yuan Xue ... Bo Wang
    An iterative self-assembling algorithm identifies the intrinsic structures in single-cell transcriptomic data and helps to discover new cell populations that are undetectable by existing methods.

    FoxP2 isoforms delineate spatiotemporal transcriptional networks for vocal learning in the zebra finch

    Zachary Daniel Burkett, Nancy F Day ... Stephanie A White
    Basal ganglia gene coexpression patterns shift across the sensorimotor critical period for vocal learning.

    Striatal action-value neurons reconsidered

    Lotem Elber-Dorozko, Yonatan Loewenstein
    The numerous reports in support of action-value representation in the striatum are based on statistical analyses that are subject to two critical confounds and, thus, this long-held belief of striatal action-value representation should be retested using different experiments and analyses.

    Self-assembly of pericentriolar material in interphase cells lacking centrioles

    Fangrui Chen, Jingchao Wu ... Anna Akhmanova
    In the absence of centrioles, components of pericentriolar material can self-organize into a single compact microtubule-organizing center through dynein-mediated transport of pericentrin-containing protein complexes if CAMSAP- and Golgi-mediated pathways of microtubule minus-end stabilization and anchoring are disabled.

    Knockdown of PHOX2B in the retrotrapezoid nucleus reduces the central CO2 chemoreflex in rats

    Silvia Cardani, Tara A Janes ... Silvia Pagliardini
    Knockdown of PHOX2B in the chemosensitive area of the retrotrapezoid nucleus of adult rats reduces CO2 responses and the expression of the proton sensors TASK2 and GPR4.

    Control of tissue development and cell diversity by cell cycle-dependent transcriptional filtering

    Maria Abou Chakra, Ruth Isserlin ... Gary D Bader
    A mathematical model predicts that cell cycle duration acts as a transcriptional filter and directly affects cell diversity in early eukaryotic development.

    The exocyst complex controls multiple events in the pathway of regulated exocytosis

    Sofía Suárez Freire, Sebastián Perez-Pandolfo ... Mariana Melani
    Gradual downregulation of each of the subunits of the evolutionary-conserved exocyst holocomplex shows that the complex is required for biogenesis, maturation, and exocytosis of secretory granules in Drosophila salivary glands.

    Intracellular glycosyl hydrolase PslG shapes bacterial cell fate, signaling, and the biofilm development of Pseudomonas aeruginosa

    Jingchao Zhang, Huijun Wu ... Luyan Ma
    A systematical study of pslG mutants at both a single cell and community level reveals the importance of intracellular glycosyl hydrolase PslG on the cell fate and biofilm development of P. aeruginosa, an opportunistic pathogen that can cause persistent infections.

    Caenorhabditis elegans PIEZO channel coordinates multiple reproductive tissues to govern ovulation

    Xiaofei Bai, Jeff Bouffard ... Andy Golden
    Depletion of the mechanosensitive ion channel PEZO-1 in C. elegans disrupts the sheath and spermathecae cells to disrupt oocyte ovulation, resulting in crushed oocytes.
