    Characterization of the kinetic cycle of an ABC transporter by single-molecule and cryo-EM analyses

    Ling Wang et al.
    The conformational dynamics of multidrug resistance protein 1 (MRP1) are tracked in real time by single-molecule fluorescence resonance energy transfer experiments, which elucidate the rate-limiting mechanism of MRP1's transport cycle.

    Identification and dynamics of the human ZDHHC16-ZDHHC6 palmitoylation cascade

    Laurence Abrami et al.
    Cycles of palmitoylation-depalmitoylation by an upstream palmitoyltransferase allow precise tuning of DHHC6 activity, which in turn regulates the abundance and function of key ER proteins involved in protein folding, degradation, ER architecture and calcium homeostasis.

    Parkin contributes to synaptic vesicle autophagy in Bassoon-deficient mice

    Sheila Hoffmann-Conaway et al.
    The presynaptic scaffolding protein Bassoon is involved in regulating neurotransmitter release by controlling synaptic vesicle pool size and vesicular protein turnover through increased ubiquitination and Parkin-dependent autophagy.

    Phospholipase D activity couples plasma membrane endocytosis with retromer dependent recycling

    Rajan Thakur et al.
    Phosphatidic acid regulates recycling of endocytosed plasma membrane vesicles in polarized cells through a retromer and Arf1 dependent process.

    The ubiquitin-proteasome system regulates focal adhesions at the leading edge of migrating cells

    Anjali Teckchandani, Jonathan A Cooper
    A ubiquitin E3 ligase localizes to focal adhesions at the front of migrating human cells where it regulates cytoskeletal dynamics by targeting a focal adhesion protein.

    Enhancer regions show high histone H3.3 turnover that changes during differentiation

    Aimee M Deaton et al.
    Nucleosomes at enhancers are unusually dynamic and change histone turnover rates during differentiation.

    A single power stroke by ATP binding drives substrate translocation in a heterodimeric ABC transporter

    Erich Stefan et al.
    Single-turnover studies reveal quantitative insights into the inner mechanics and unfold hidden facets in the conformational coupling of ATP binding, hydrolysis, and substrate translocation by ABC transporters.

    CCR4, a RNA decay factor, is hijacked by a plant cytorhabdovirus phosphoprotein to facilitate virus replication

    Zhen-Jia Zhang et al.
    A cytorhabdovirus phosphoprotein hijacks host CCR4 to trigger turnover of viral nucleoprotein (N)-bound cellular RNAs, thereby releasing nascent RNA-free N protein molecules to bind viral genomic RNAs for optimal replication.

    A balance of positive and negative regulators determines the pace of the segmentation clock

    Guy Wiedermann et al.
    Computational modelling together with experimental manipulation indicate that the stability and turnover of activated Notch is inextricably linked to the regulation of the pace of segmentation clock gene expression in the presomitic mesoderm.

    Structural basis of interprotein electron transfer in bacterial sulfite oxidation

    Aaron P McGrath et al.
    A structural and functional analysis of the electron transfer complex between a sulfite oxidase and its redox protein partner reveals an elegant compromise between the requirements for fast and efficient electron transfer and reaction specificity.
