    Promiscuous binding by Hsp70 results in conformational heterogeneity and fuzzy chaperone-substrate ensembles

    Rina Rosenzweig et al.
    Multiple chaperone binding sites on substrates suggest a mechanism by which the Hsp70 chaperone can circumvent kinetic traps in protein folding.

    A Dynamic molecular basis for malfunction in disease mutants of p97/VCP

    Anne K Schuetz, Lewis E Kay
    Point mutations in a ubiquitous human ATPase called p97/VCP deregulate inter-domain communication, resulting in impaired binding of an adaptor that recruits p97 to endosomal pathways and leading to a degenerative disease of bone, muscle and neurons.

    Conserved conformational selection mechanism of Hsp70 chaperone-substrate interactions

    Ashok Sekhar et al.
    NMR-based flux measurements show that both bacterial and human Hsp70 chaperones interact with helical, as well as sheet substrates predominantly through a conformational selection mechanism.

    Molecular Chaperones: Confirmation for conformational selection

    Yajun Jiang, Charalampos G Kalodimos
    NMR studies settle part of a long-standing debate about the mechanism used by the Hsp70 chaperone to recognize substrates.

    Insulin signaling controls neurotransmission via the 4eBP-dependent modification of the exocytotic machinery

    Rebekah Elizabeth Mahoney et al.
    By regulating protein translation within the neuron, insulin signaling can control neuronal activity by altering the release of neurotransmitter molecules.

    Complexin induces a conformational change at the membrane-proximal C-terminal end of the SNARE complex

    Ucheor B Choi et al.
    Complexin can have two conformations when bound to a ternary SNARE complex, one of which induces a conformational change of the SNARE complex at the C-terminus.

    Tuning site-specific dynamics to drive allosteric activation in a pneumococcal zinc uptake regulator

    Daiana A Capdevila et al.
    Internal dynamics play a crucial functional role in MarR (multiple antibiotic resistance repressor) proteins and their role reconciles the distinct allosteric mechanisms proposed previously.

    An unfolded protein-induced conformational switch activates mammalian IRE1

    G Elif Karagöz et al.
    ER-stress sensing mechanism of the unfolded protein response sensor/transducer IRE1 is conserved from yeast to mammals, where in mammals, unfolded protein binding to IRE1's ER lumenal domain is coupled to its oligomerization and activation through an allosteric conformational change.

    Implications of the differing roles of the β1 and β3 transmembrane and cytoplasmic domains for integrin function

    Zhenwei Lu et al.
    Diverse biophysical properties of β1 and β3 integrin transmembrane and cytoplasmic domains result in distinct mechanisms of integrin activation and function.
