    The active-zone protein Munc13 controls the use-dependence of presynaptic voltage-gated calcium channels

    Nathaniel Calloway et al.
    Munc13, a protein that is essential for exocytosis, controls the behavior of voltage gated calcium channels and shapes synaptic plasticity on fast time scales.

    Kv2.1 mediates spatial and functional coupling of L-type calcium channels and ryanodine receptors in mammalian neurons

    Nicholas C Vierra et al.
    A potassium channel, as a nonconducting function, organizes compartmentalized neuronal calcium signaling microdomains via structural and functional coupling of plasma membrane and endoplasmic reticulum calcium channels.

    Molecular mechanisms of gating in the calcium-activated chloride channel bestrophin

    Alexandria N Miller et al.
    Cryo-EM structures of the gating cycle of bestrophin reveal the molecular underpinnings of activation and inactivation gating in this calcium-activated chloride channel and reveal a surprisingly wide pore.

    A native prokaryotic voltage-dependent calcium channel with a novel selectivity filter sequence

    Takushi Shimomura et al.
    The small glycine residue in the Cav selectivity filter is an overlooked feature that determines Ca2+ selectivity and provides new insight into the Ca2+ selectivity mechanism conserved from prokaryotes to eukaryotes.

    A potent voltage-gated calcium channel inhibitor engineered from a nanobody targeted to auxiliary CaVβ subunits

    Travis J Morgenstern et al.
    A novel engineered protein that uncouples electrical signals from downstream biological responses in excitable cells provides a unique investigative tool with potential therapeutic applications.

    Proteolytic maturation of α2δ represents a checkpoint for activation and neuronal trafficking of latent calcium channels

    Ivan Kadurin et al.
    Multiple roles of the auxiliary calcium channel α2δ subunits require proteolytic cleavage of the precursor protein into α2 and δ.

    Calcium-dependent electrostatic control of anion access to the pore of the calcium-activated chloride channel TMEM16A

    Andy KM Lam, Raimund Dutzler
    Ion conduction in the calcium-activated chloride channel TMEM16A is directly regulated by calcium, which binds to a site close to the pore thereby shaping the electrostatics at its intracellular entrance.

    Novel charged sodium and calcium channel inhibitor active against neurogenic inflammation

    Seungkyu Lee et al.
    A cationic molecule derived from an uncharged Cav2.2 calcium channel inhibitor powerfully inhibits both sodium and calcium channels with extracellular application and inhibits both pain and neurogenic inflammation.

    Cell-specific exon methylation and CTCF binding in neurons regulate calcium ion channel splicing and function

    Eduardo Javier López Soto, Diane Lipscombe
    Cell-specific alternative splicing of the synaptic calcium channel gene Cacna1b is controlled by exon hypomethylation and CTCF binding and is disrupted following nerve injury.

    Dendritic small conductance calcium-activated potassium channels activated by action potentials suppress EPSPs and gate spike-timing dependent synaptic plasticity

    Scott L Jones et al.
    The activation of small-conductance calcium-activated potassium channels in spines by action potentials regulates the induction of spike-timing dependent synaptic plasticity during low-frequency single action potential–EPSP pairing.
