    Recognition and cleavage of human tRNA methyltransferase TRMT1 by the SARS-CoV-2 main protease

    Angel D'Oliviera, Xuhang Dai ... Jeffrey S Mugridge
    The SARS-CoV-2 main protease specifically cleaves a conserved sequence in the human tRNA modifying enzyme TRMT1, resulting in reduced tRNA binding and the complete loss of TRMT1-mediated tRNA methyltransferase activity.

    Heparan sulfates are critical regulators of the inhibitory megakaryocyte-platelet receptor G6b-B

    Timo Vögtle, Sumana Sharma ... Yotis A Senis
    Heparan sulfates in the vessel wall bind and regulate signaling from the megakaryocyte/platelet-specific inhibitory receptor G6b-B, a critical regulator of platelet homeostasis.

    Optogenetically induced low-frequency correlations impair perception

    Anirvan Nandy, Jonathan J Nassi ... John Reynolds
    Low-frequency correlations among neurons in monkey visual area V4 impair the animal's ability to perform an attention-demanding task, suggesting a causal role of these fluctuations in perception.

    Tenectin recruits integrin to stabilize bouton architecture and regulate vesicle release at the Drosophila neuromuscular junction

    Qi Wang, Tae Hee Han ... Mihaela Serpe
    Characterization of Tnc as a selective integrin ligand at the Drosophila NMJ allows for unprecedented insights into our understanding of extracellular matrix/integrin interactions at synaptic locations and reveals novel, distinct presynaptic and postsynaptic integrin functions.

    Intrinsic mechanical sensitivity of mammalian auditory neurons as a contributor to sound-driven neural activity

    Maria C Perez-Flores, Eric Verschooten ... Ebenezer N Yamoah
    In vitro and in vivo physiological analyses reveal that mammalian auditory neuron intrinsic mechanical sensitivity contributes to sound-evoked activity and explains other previously unexplained auditory neuron features.

    The COMA complex interacts with Cse4 and positions Sli15/Ipl1 at the budding yeast inner kinetochore

    Josef Fischböck-Halwachs, Sylvia Singh ... Franz Herzog
    The chromosomal passenger complex interacts with the inner kinetochore COMA complex through the Ctf19 C-terminus in vitro which is shown to be important for mediating accurate chromosome segregation.

    Associative learning drives longitudinally graded presynaptic plasticity of neurotransmitter release along axonal compartments

    Aaron Stahl, Nathaniel C Noyes ... Seth M Tomchik
    Experience alters neurotransmitter release from different axonal compartments in different ways, allowing a set of neurons to coherently modulate behavior through diverse actions on multiple downstream circuits.

    Pathway-specific effects of ADSL deficiency on neurodevelopment

    Ilaria Dutto, Julian Gerhards ... Travis H Stracker
    Analysis of adenylosuccinate lyase (ADSL) deficiency in multiple experimental systems reveals cell and organismal phenotypes and impaired neurodevelopment due to the attenuation of ADSL's roles in distinct pathways.

    Mitochondria supply ATP to the ER through a mechanism antagonized by cytosolic Ca2+

    Jing Yong, Helmut Bischof ... Randal J Kaufman
    ATP enters the endoplasmic reticulum (ER) lumen through an SLC35B1/AXER-dependentCaATiER mechanism, and ATP usage in the ER renders 'anti-Warburg' effect by increasing ATP regeneration from OxPhos while decreasing glycolysis.
