    Robust cullin-RING ligase function is established by a multiplicity of poly-ubiquitylation pathways

    Spencer Hill et al.
    Human cullin-RING ligases are buffered to a much greater extent than had been previously appreciated, and the roles of ubiquitin chain extension enzymes are far more nuanced at physiological concentrations.

    ZMYND10 functions in a chaperone relay during axonemal dynein assembly

    Girish R Mali et al.
    Chaperoning defects in axonemal dynein subunits trigger proteostatic clearance of dynein motors opening up the possibility of trialling proteostasis modulators to treat the motile ciliopathy primary ciliary dyskinesia (PCD).

    Unique-region phosphorylation targets LynA for rapid degradation, tuning its expression and signaling in myeloid cells

    Ben F Brian IV et al.
    The ubiquitin ligase c-Cbl preferentially targets unique-region phosphorylated LynA for rapid degradation, regulating its expression and differentially tuning signaling responsiveness in macrophages and mast cells.

    The metalloproteinase Papp-aa controls epithelial cell quiescence-proliferation transition

    Chengdong Liu et al.
    Zinc metalloproteinase Papp-aa-mediated Igfbp5 proteolysis functions as a [Ca2+]-regulated molecular switch linking IGF signaling to epithelial cell proliferation and bone calcification.

    The CHORD protein CHP-1 regulates EGF receptor trafficking and signaling in C. elegans and in human cells

    Andrea Haag et al.
    The co-chaperone CHORDC1 is specifically required for epidermal growth factor receptor trafficking and signaling in Caenorhabditis elegans and in human cells.

    A processive rotary mechanism couples substrate unfolding and proteolysis in the ClpXP degradation machinery

    Zev A Ripstein et al.
    Understanding of bacterial protein degradation is illuminated by cryo-EM structures of the substrate-bound ClpXP complex from Neisseria meningitidis at 2.3 to 3.3 Å resolution.

    General decapping activators target different subsets of inefficiently translated mRNAs

    Feng He et al.
    Dhh1, Pat1, and Lsm1 target subsets of cellular mRNAs for decapping via interactions of these regulatory proteins with the C-terminal domain of Dcp2, the catalytic component of the decapping enzyme.

    Active presynaptic ribosomes in the mammalian brain, and altered transmitter release after protein synthesis inhibition

    Matthew S Scarnati et al.
    Local presynaptic protein synthesis occurring at established nerve terminals in the mammalian brain provides a mechanism for rapidly controlling or restoring presynaptic proteins that affect neurotransmitter release and presynaptic efficiency.

    SnRK1-triggered switch of bZIP63 dimerization mediates the low-energy response in plants

    Andrea Mair et al.
    The transcription factor bZIP63 is a key regulator of the starvation response in the model plant Arabidopsis thaliana and is directly targeted by the kinase SnRK1.

    An extensive program of periodic alternative splicing linked to cell cycle progression

    Daniel Dominguez et al.
    Extensive periodic regulation of alternative splicing during the cell cycle in genes is linked to cell cycle functions, and involves an auto-inhibitory mechanism that uses the protein kinase CLK1.
