    Allosteric mechanism for KCNE1 modulation of KCNQ1 potassium channel activation

    Georg Kuenze et al.
    An integrative structural biology approach provides refined models of the KCNQ1-KCNE1 channel complex, which propose a new mechanism to explain how KCNE1 modulates KCNQ1 channel activation.

    Activation mechanism of ATP-sensitive K+ channels explored with real-time nucleotide binding

    Michael Puljung et al.
    A combined FRET- and electrophysiology-based approach is used to study ATP/ADP ADP binding to the stimulatory nucleotide binding site of ATP-sensitive K+ channels and investigate their activation mechanism.

    The ion selectivity filter is not an activation gate in TRPV1-3 channels

    Andrés Jara-Oseguera et al.
    The TRPV1, TRPV2 and TRPV3 channels are gated on the cytosolic side of the pore, whereas structural changes in the ion selectivity filter associated with activation don't control cation access.

    Conformational change within the extracellular domain of B cell receptor in B cell activation upon antigen binding

    Zhixun Shen et al.
    Conformational changes occur within extracellular domain of BCR upon antigen engagement, and these conformational changes are related with the strength of BCR activation and are distinct in IgM- and IgG-BCR.

    Hydrogen bonds as molecular timers for slow inactivation in voltage-gated potassium channels

    Stephan A Pless et al.
    Tuning the strength of inter- and intra-subunit hydrogen bonds can control potassium flux across biological membranes.

    Activation of the archaeal ion channel MthK is exquisitely regulated by temperature

    Yihao Jiang et al.
    Temperature-sensitivity of archaebacterial potassium channel MthK is regulated by RCK domain via alteration of allosteric coupling.

    Piezo1 forms a slowly-inactivating mechanosensory channel in mouse embryonic stem cells

    Josefina Inés del Mármol et al.
    Piezo1 exhibits markedly different kinetic behavior in different cellular contexts.

    Chronic postnatal chemogenetic activation of forebrain excitatory neurons evokes persistent changes in mood behavior

    Sthitapranjya Pati et al.
    Enhanced Gq-signaling-mediated activation of forebrain excitatory neurons in postnatal life programs enhanced anxiety-, despair- and schizophrenia-like behavior, recapitulating key aspects of the behavioral consequences of early life adversity.

    Molecular mechanisms of human P2X3 receptor channel activation and modulation by divalent cation bound ATP

    Mufeng Li et al.
    Structural, computational and functional approaches reveal the role of an extended acidic chamber near the nucleotide binding site in activation of P2X3 receptor channels by divalent-bound ATP.

    Mechanism of activation at the selectivity filter of the KcsA K+ channel

    Florian T Heer et al.
    The transmembrane helices forming the pore determine the conductance of the selectivity filter through allosteric interactions.
