    Scleraxis-lineage cell depletion improves tendon healing and disrupts adult tendon homeostasis

    Katherine T Best, Antonion Korcari ... Alayna E Loiselle
    Adult Scleraxis-lineage cells are not required for successful tendon healing but are required for maintenance of tendon homeostasis.

    Distinct expression requirements and rescue strategies for BEST1 loss- and gain-of-function mutations

    Qingqing Zhao, Yang Kong ... Tingting Yang
    BEST1 autosomal dominant loss-of-function mutations surprisingly behave in a dominant-negative manner, whereas gain-of-function mutations exhibit a strong dominant effect that necessitates CRISPR/Cas9-mediated suppression of the endogenous mutant allele in gene therapy.

    Perception of an object’s global shape is best described by a model of skeletal structure in human infants

    Vladislav Ayzenberg, Stella Lourenco
    Six- to twelve-month old infants, who have little linguistic or object experience, classify objects by relying on a invariant representation of global shape known as the shape skeleton.

    EDF1 coordinates cellular responses to ribosome collisions

    Niladri K Sinha, Alban Ordureau ... Rachel Green
    Endothelial Differentiation Factor 1 (EDF1) plays a critical role in driving mRNA-specific quality control and global transcriptional responses in response to ribosome collisions.

    Patient-specific mutations impair BESTROPHIN1’s essential role in mediating Ca2+-dependent Cl- currents in human RPE

    Yao Li, Yu Zhang ... Tingting Yang
    A multidisciplinary platform featured by patient-derived RPEs is established to study the disease-causing mechanisms of BEST1 mutations, and demonstrates gene-supplemented rescue of the mutation-caused deficiency in Ca2+-dependent Cl- current in human RPE.

    Demographic reconstruction from ancient DNA supports rapid extinction of the great auk

    Jessica E Thomas, Gary R Carvalho ... Michael Knapp
    Reconstruction of great auk population dynamics suggests that hunting pressure alone could have been responsible for their extinction, demonstrating that even abundant, widespread species can be vulnerable to intense exploitation.

    Molecular mechanisms of gating in the calcium-activated chloride channel bestrophin

    Alexandria N Miller, George Vaisey, Stephen B Long
    Cryo-EM structures of the gating cycle of bestrophin reveal the molecular underpinnings of activation and inactivation gating in this calcium-activated chloride channel and reveal a surprisingly wide pore.

    Ubiquitination drives COPI priming and Golgi SNARE localization

    Swapneeta S Date, Peng Xu ... Todd R Graham
    The ability of COPI to bind polyubiquitin is a key determinant for SNARE incorporation into intracellular vesicles and for maintenance of a functional Golgi complex.
