    A comprehensive search for calcium binding sites critical for TMEM16A calcium-activated chloride channel activity

    Jason Tien et al.
    The identification of four acidic amino acids as potential calcium-binding residues in the TMEM16A calcium-activated chloride channel furthers the molecular understanding of this ion channel family.

    Calcium influx through CRAC channels controls actin organization and dynamics at the immune synapse

    Catherine A Hartzell et al.
    By restricting actin polymerization to the perimeter of the immune synapse and promoting depolymerization, calcium influx drives centripetal actin flow, which confines CRAC channels and the endoplasmic reticulum to the synapse center.

    NG2 glial cells integrate synaptic input in global and dendritic calcium signals

    Wenjing Sun et al.
    NG2 glial cells respond to synaptic input with calcium signals in the absence of action potentials and process synaptic depolarizations with somatic and dendritic voltage gated channels.

    Chronic social isolation reduces 5-HT neuronal activity via upregulated SK3 calcium-activated potassium channels

    Derya Sargin et al.
    Serotonin neurons in chronically isolated mice become less responsive to excitatory stimulation, but inhibiting a distinctive calcium-activated potassium channel can restore both neuronal activity and behavior.

    Structural mechanism of ligand activation in human calcium-sensing receptor

    Yong Geng et al.
    L-amino acids are agonists of calcium-sensing receptor, and act jointly with calcium and phosphate ions to control receptor function.

    Inhibition enhances spatially-specific calcium encoding of synaptic input patterns in a biologically constrained model

    Daniel B Dorman et al.
    Inhibition enhances the spatial specificity of high calcium influx for cooperatively stimulated synapses, suggesting that inhibitory inputs may regulate both synapse-specific and heterosynaptic plasticity to support learning and memory.

    Cholinergic modulation of hippocampal calcium activity across the sleep-wake cycle

    Heng Zhou et al.
    Dynamic calcium activity in the hippocampus changes markedly across behavioral and physiological states and depends on muscarinic acetylcholine receptor activation.

    Mechanism and consequence of abnormal calcium homeostasis in Rett syndrome astrocytes

    Qiping Dong et al.
    Increased spontaneous calcium activity in Rett syndrome astrocytes is a key cell-autonomous phenotype that affects synaptic function and network activity.

    Protein kinase C is a calcium sensor for presynaptic short-term plasticity

    Diasynou Fioravante et al.
    Genetic and electrophysiology experiments provide the first direct evidence that protein kinase C is a calcium-sensing protein in post-tetanic potentiation, a form of synaptic plasticity that supports short-term memory.

    Recurrent gain of function mutation in calcium channel CACNA1H causes early-onset hypertension with primary aldosteronism

    Ute I Scholl et al.
    A novel Mendelian disease featuring early-onset hypertension is caused by a recurrent gain of function mutation in CACNA1H, which encodes the voltage-gated calcium channel Cav3.2.
