Na+/Ca2+ Exchanger

The Na+/Ca2+ exchanger (NCX) is a low affinity, high capacitance calcium antiporter membrane protein that functions to regulate intracellular calcium concentrations. It is located on the plasma, mitochondrial and endoplasmic reticular membranes of excitable cells.

The Na+/Ca2+ exchanger (NCX) is a low affinity, high capacitance calcium antiporter membrane protein that functions to regulate intracellular calcium concentrations. It is located on the plasma, mitochondrial and endoplasmic reticular membranes of excitable cells. Using the electrochemical gradient of Na+, one Ca2+ ion is transported out of the cell in exchange for three Na+ ions.

The Na+/Ca2+ exchanger compliments the high affinity, low capacitance Ca2+-ATPase and together, they are involved in a variety of cellular functions including control of neurosecretion, relaxation of cardiac muscle, maintenance of intracellular Ca2+ stores in the endoplasmic and sarcoplasmic reticuli and excitation-contraction coupling. Under normal physiological conditions, Na+/Ca2+ exchangers export Ca+ from the cell. However, under cellular stress, such as excitotoxicity, they can switch to 'reverse mode,' which has a protective effect.

    Epilepsy is a brain disease that affects 60 million people globally. More than 20 anti-seizure drugs are currently available, but these do not address the underlying causes of the condition. This poster summarizes current knowledge about the development of the condition and highlights some approaches that have disease-modifying effects in proof-of-concept studies.
