    RNA polymerase II stalling at pre-mRNA splice sites is enforced by ubiquitination of the catalytic subunit

    Laura Milligan et al.
    Ubiquitination close to the active site of RNAPII occurs in response to RNA processing events and is linked to transcriptional pausing, which is released following Bre5-Ubp3 mediated deubiquitination associated with the nascent transcript.

    A proteomic chronology of gene expression through the cell cycle in human myeloid leukemia cells

    Tony Ly et al.
    Quantitative analysis of protein and mRNA expression across a minimally perturbed cell cycle in human myeloid cells has identified myeloid-specific and cell cycle-regulated gene expression, including examples of isoform- and phosphorylation-specific regulation, with all data made available in a searchable, online database.

    Structures of the ATP-fueled ClpXP proteolytic machine bound to protein substrate

    Xue Fei et al.
    Cryo-EM structures of the ClpXP protease reveal how protein substrates are bound, show how spiral ClpX hexamers bind symmetry-mismatched heptameric ClpP rings, and suggest mechanisms for processive substrate translocation.

    The serine protease hepsin mediates urinary secretion and polymerisation of Zona Pellucida domain protein uromodulin

    Martina Brunati et al.
    Hepsin is the first protease identified to modulate specific cleavage and secretion of a Zona Pellucida domain protein, uromodulin.

    Homozygous YME1L1 mutation causes mitochondriopathy with optic atrophy and mitochondrial network fragmentation

    Bianca Hartmann et al.
    Mutations affecting a nuclear encoded metalloprotease cause of a new form of mitochondriopathy, highlighting the importance of this protease for mitochondrial function in humans.

    Increased expression of heme-binding protein 1 early in Alzheimer's disease is linked to neurotoxicity

    Oleksandr Yagensky et al.
    Increased levels of brain Hebp1 starting from the presymptomatic stage of Alzheimer’s disease contributes to progressive neuronal loss by triggering mitochondrial-dependent apoptosis in neurons exposed to elevated heme.

    Proteasome dysfunction triggers activation of SKN-1A/Nrf1 by the aspartic protease DDI-1

    Nicolas J Lehrbach, Gary Ruvkun
    Post-translational processing of the SKN-1A/Nrf1 transcription factor regulates proteasome expression.

    Proteotoxicity from aberrant ribosome biogenesis compromises cell fitness

    Blake W Tye et al.
    Rapidly proliferating cells are at risk of compromised cell fitness due to proteostasis collapse from perturbations that interfere with ribosome biogenesis.

    Structure of Vps4 with circular peptides and implications for translocation of two polypeptide chains by AAA+ ATPases

    Han Han et al.
    Structural and biochemical studies indicate that AAA+ ATPase employ a general mechanism to translocate a variety of substrates, including extended polypeptides, hairpins, crosslinked chains, and chains conjugated to other molecules.

    The GTPase Nog1 co-ordinates the assembly, maturation and quality control of distant ribosomal functional centers

    Purnima Klingauf-Nerurkar et al.
    The GTPase Nog1 orchestrates stalk assembly, peptidyl transferase centre maturation and polypeptide exit tunnel quality control.
