    Structural basis for allosteric control of the SERCA-Phospholamban membrane complex by Ca2+ and phosphorylation

    Daniel K Weber, U Venkateswara Reddy ... Gianluigi Veglia
    A spectroscopic analysis of the sarco(endo)plasmic reticulum Ca2+-ATPase (SERCA)-phospholamban membrane complex reveals the importance of the relative transmembrane orientation for inhibition or activation of the ATPase.

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

    Zhenwei Lu, Sijo Mathew ... Roy Zent
    Diverse biophysical properties of β1 and β3 integrin transmembrane and cytoplasmic domains result in distinct mechanisms of integrin activation and function.

    Structure and physiological function of the human KCNQ1 channel voltage sensor intermediate state

    Keenan C Taylor, Po Wei Kang ... Charles R Sanders
    The intermediate state conformation of the human KCNQ1 potassium channel voltage sensor domain was determined, validated, and shown to be conductive under physiological conditions.

    Dynamic allostery in substrate binding by human thymidylate synthase

    Jeffrey P Bonin, Paul J Sapienza, Andrew L Lee
    The mechanism of substrate binding cooperativity in human thymidylate synthase does not derive from millisecond dynamic interconversion between active and inactive conformations in solution, but instead results primarily from differential changes in faster side-chain motions (conformational entropy), facilitated by a disordered N-terminus.

    Local frustration determines loop opening during the catalytic cycle of an oxidoreductase

    Lukas S Stelzl, Despoina AI Mavridou ... Christina Redfield
    The cysteine pair oxidation state in nDsbD acts as a ‘switch’ controlling the presence or absence of frustration in the active-site and determining the dynamic behavior of the cap loop.

    An order-to-disorder structural switch activates the FoxM1 transcription factor

    Aimee H Marceau, Caileen M Brison ... Seth M Rubin
    Structural and biochemical analysis reveals that two intrinsically disordered domains of the transcription factor FoxM1 co-fold to form an autoinhibited conformation, which is disrupted by a specific activating phosphorylation event.
