Our research focuses on how intracellular Ca2+, the ultimate signal of membrane excitability, regulates membrane excitability and the consequent function of excitable cells. We have discovered and described multiple mechanisms that control Ca2+ influx through voltage-gated Ca2+ channels and feedback mechanisms by which internal calcium regulates other channels that influence Ca2+ channel function. The work has entailed structure-function analyses of ion channels and their regulatory subunits and studies of mutations that lead to inherited channelopathies such as cardiac arrhythmias and epilepsy.
