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.

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.

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.

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

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.

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.

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

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.

Epigenetic modifications to DNA can regulate E3 ubiquitin ligase activity in human cells.

Analysis of a variant without lysine in the intracellular domain reveals a ubiquitylation-independent signalling activity of the DSL ligand Delta and novel functions of the Neuralized and Mindbomb1 E3-ligases during Notch signalling.
