  1. Episode 51: November 2018

    In this episode, we hear about mammals moving to the suburbs, LSD and the brain, publication bias, contagious cancers, and the effect of climate change on mosquito-borne diseases.
    1. Cell Biology

    Complementary α-arrestin-ubiquitin ligase complexes control nutrient transporter endocytosis in response to amino acids

    Vasyl Ivashov et al.
    Metabolic cues enlist ubiquitin ligase adaptors for the selective control of cellular nutrient acquisition strategies.
    1. Chromosomes and Gene Expression

    Multi-protein bridging factor 1(Mbf1), Rps3 and Asc1 prevent stalled ribosomes from frameshifting

    Jiyu Wang et al.
    An eukaryotic specific system cooperates with the ribosome quality control pathway to maintain the reading frame during translation of slowly translated sequences.
    1. Neuroscience

    Doc2B acts as a calcium sensor for vesicle priming requiring synaptotagmin-1, Munc13-2 and SNAREs

    Sébastien Houy et al.
    Doc2B functions in two distinct vesicle priming steps; membrane localization occludes upstream Ca2+-dependent priming, whereas Ca2+-binding and interaction with synaptotagmin-1, SNAREs, and Munc13-2 are involved in downstream priming, which makes vesicles readily releasable.
    1. Neuroscience

    Vocal development in a Waddington landscape

    Yayoi Teramoto et al.
    An integrated landscape framework shows how the coordinated changes in vocal apparatus, muscles, nervous system, and social interaction together influence the trajectory of vocal development.

    Identification of a Munc13-sensitive step in chromaffin cell large dense-core vesicle exocytosis

    Kwun Nok M Man et al.
    Munc13 proteins are key determinants of large dense-core vesicle (LDCV)-dependent catecholamine release in chromaffin cells.

    Synaptotagmin-1 is the Ca2+ sensor for fast striatal dopamine release

    Aditi Banerjee et al.
    Genetic and electrophysiological analyses reveal calcium-triggering mechanisms for dopamine release in the striatum that may enable fast and slow dopamine coding.

    Structural basis for COMPASS recognition of an H2B-ubiquitinated nucleosome

    Evan J Worden et al.
    The structure of the COMPASS methyltransferase bound to an H2B-ubiquitinated nucleosome provides insights into mechanisms of trans-histone cross-talk and the dynamic role of H2B ubiquitination in stimulating histone methylation.

    Synaptotagmin 7 functions as a Ca2+-sensor for synaptic vesicle replenishment

    Huisheng Liu et al.
    Two proteins—synaptotagmin 7 and calmodulin—have central roles in the calcium-dependent pathway that maintains synaptic transmission.
    1. Microbiology and Infectious Disease

    Streptomyces exploration is triggered by fungal interactions and volatile signals

    Stephanie E Jones et al.
    Exploratory growth is a newly discovered mode of Streptomyces growth that it is stimulated by fungi, is pH responsive, and can be communicated to other – physically separated – streptomycetes through airborne compounds.
