    Distinct regulatory ribosomal ubiquitylation events are reversible and hierarchically organized

    Danielle M Garshott et al.
    A hierarchical relationship among highly conserved regulatory ribosomal ubiquitylation events and the presence of antagonistic deubiquitylating enzymes suggests a dynamic ubiquitin code impacts ribosome-associated activities.

    Negative regulation of autophagy by UBA6-BIRC6–mediated ubiquitination of LC3

    Rui Jia, Juan S Bonifacino
    An ensemble of the ubiquitin-activating enzyme UBA6 and ubiquitin-conjugating enzyme/ubiquitin-ligase BIRC6 mediates ubiquitination of LC3, targeting the latter for proteasomal degradation and thus attenuating autophagic degradation of cellular substrates.

    Cyclophilin A-regulated ubiquitination is critical for RIG-I-mediated antiviral immune responses

    Wei Liu et al.
    CypA boosts RIG-I-mediated antiviral immune responses via enhancing K63-linked ubiquitination of RIG-I and inhibiting K48-linked ubiquitination of MAVS.

    A PALB2-interacting domain in RNF168 couples homologous recombination to DNA break-induced chromatin ubiquitylation

    Martijn S Luijsterburg et al.
    A new mechanism is uncovered by which the RNF168 ubiquitin ligase couples PALB2-dependent homologous recombination to H2A ubiquitylation to promote DNA repair and preserve genome integrity.

    G-protein-coupled receptors regulate autophagy by ZBTB16-mediated ubiquitination and proteasomal degradation of Atg14L

    Tao Zhang et al.
    Under normal nutritional conditions, G-protein coupled receptors can control autophagy by regulating the degradation of key autophagic regulator Atg14L through ZBTB16-mediated ubiquitination and proteasome degradation.

    CB1-receptor-mediated inhibitory LTD triggers presynaptic remodeling via protein synthesis and ubiquitination

    Hannah R Monday et al.
    CB1-receptor-mediated inhibitory long-term depression (LTD) relies on both protein synthesis and ubiquitination to elicit structural changes that underlie long-term reduction of GABA release.

    DET1-mediated degradation of a SAGA-like deubiquitination module controls H2Bub homeostasis

    Amr Nassrallah et al.
    Light signaling components interact with a histone H2B deubiquitination module, adjusting chromatin states at global level during Arabidopsis seedling development.

    Ubiquitination-dependent control of sexual differentiation in fission yeast

    Fabrizio Simonetti et al.
    The RNA-binding protein Mmi1 targets its own inhibitor Mei2 for ubiquitination by the E3 ubiquitin ligase Not4/Mot2 in order to preserve its role in meiotic mRNA decay during vegetative growth.

    Cross-talk between PRMT1-mediated methylation and ubiquitylation on RBM15 controls RNA splicing

    Li Zhang et al.
    Inhibiting PRMT1 enzymatic activity promotes megakaryocyte terminal differentiation via RBM15-mediated RNA metabolism, which is dysregulated in hematological malignancies.

    Mfn2 ubiquitination by PINK1/parkin gates the p97-dependent release of ER from mitochondria to drive mitophagy

    Gian-Luca McLelland et al.
    A crucial step during the mitophagy cascade involves the disassembly of connections between mitochondria and the endoplasmic reticulum via the retrotranslocation of Mfn2 tethering complexes by the Parkinson's disease genes PARKIN and PINK1, as well as the ATPase VCP/p97.
