    Molecular structures of the human Slo1 K+ channel in complex with β4

    Xiao Tao, Roderick MacKinnon
    The structures of Slo1 in complex with b4 imply that the auxiliary beta subunits modulate the channel's gating properties through stabilizing ‘pre-existing’ conformations rather than creating new ones.

    Slo1 is the principal potassium channel of human spermatozoa

    Nadja Mannowetz et al.
    Potassium ions enter and leave human sperm cells via a calcium-dependent ion channel that is also pH-independent.

    IK1 channels do not contribute to the slow afterhyperpolarization in pyramidal neurons

    Kang Wang et al.
    The slow afterhyperpolarization that follows a burst of action potentials is a powerful regulator of neuronal excitability and is not due to IK1 (KCNN4), a member of the SK channel family.

    The Ca2+-activated K+ current of human sperm is mediated by Slo3

    Christoph Brenker et al.
    The principal potassium ion channel in human sperm, Slo3, is primarily activated by calcium ions and controls the membrane potential of human sperm by intracellular calcium ion levels rather than intracellular pH.

    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.

    BK channel inhibition by strong extracellular acidification

    Yu Zhou et al.
    Analysis of iconic and gating currents of wild type and mutated BK channels reveals a strong inhibition of this channel by extracellular acidification and elucidates the underlying mechanism that is potentially applicable to other voltage-dependent cation channels.

    Mechanisms underlying sharpening of visual response dynamics with familiarity

    Sukbin Lim
    Changes in neural response dynamics observed with visual learning provide a novel means to dissect synaptic plasticity and its interplay with slow negative feedback via firing rate adaptation.

    Dynamics of human protein kinase Aurora A linked to drug selectivity

    Warintra Pitsawong et al.
    Slow conformational changes after drug binding rationalize selectivity, affinity and long on-target residence time for kinase inhibitors.
