    Mechanism of ubiquitin ligation and lysine prioritization by a HECT E3

    Hari B Kamadurai et al.
    Structural studies reveal the mechanism by which a HECT E3 ubiquitin ligase carries out E2-to-E3-to-substrate ubiquitin transfer and prioritizes target lysines for ubiquitination.

    Requirement of Smurf-mediated endocytosis of Patched1 in sonic hedgehog signal reception

    Shen Yue et al.
    Smurf1 and Smurf2 have essential functions in the mammalian Shh signaling pathway, binding to and ubiquitylating Patched1, leading to its endocytosis and subsequent degradation in lysosomes.

    Insights into the ubiquitin transfer cascade catalyzed by the Legionella effector SidC

    David Jon Wasilko et al.
    Structural and biochemical studies reveal the molecular mechanisms for ubiquitin transfer by two unique bacterial ubiquitin E3 ligases.

    Spatial sequestration and detoxification of Huntingtin by the ribosome quality control complex

    Junsheng Yang et al.
    A genome-wide screen in yeast reveals that key proteins in ribosome quality control also regulate mutant Huntingtin aggregation and toxicity.

    CHIP as a membrane-shuttling proteostasis sensor

    Yannick Kopp et al.
    The mechanism is revealed that connects the protein degradation machinery to cellular membrane-bound compartments during proteostasis stress in mammalian cells.

    KLHL41 stabilizes skeletal muscle sarcomeres by nonproteolytic ubiquitination

    Andres Ramirez-Martinez et al.
    KLHL41 acts as a poly-ubiquitin dependent chaperone that prevents the formation of pathogenic nebulin aggregates associated with muscle disease.

    A conformational switch regulates the ubiquitin ligase HUWE1

    Bodo Sander et al.
    The cancer-associated human ubiquitin ligase HUWE1 can adopt an auto-inhibited dimeric state, whose occupancy is regulated by competing intra- and intermolecular interactions of the dimerization region and by the tumor suppressor p14ARF.

    A conserved quality-control pathway that mediates degradation of unassembled ribosomal proteins

    Min-Kyung Sung et al.
    Tom1 is the ubiquitin ligase in yeast that anchors a protein quality control pathway that rapidly eliminates ribosomal proteins that fail to assemble into ribosomes.

    HSF-1 activates the ubiquitin proteasome system to promote non-apoptotic developmental cell death in C. elegans

    Maxime J Kinet et al.
    A pathway controlling non-apoptotic developmental cell death engages non-canonical death-promoting activities of the stress factor HSF-1, which, in turn, activates specific components of the ubiquitin-mediated degradation machinery.

    A potent voltage-gated calcium channel inhibitor engineered from a nanobody targeted to auxiliary CaVβ subunits

    Travis J Morgenstern et al.
    A novel engineered protein that uncouples electrical signals from downstream biological responses in excitable cells provides a unique investigative tool with potential therapeutic applications.
