Kurzfassung:
We characterized an activation mechanism of the human LTRPC2 protein, a member of the transient receptor potential family of ion channels, and demonstrated that LTRPC2 mediates Ca 2+ influx into immunocytes. Intracellular pyrimidine nucleotides, adenosine 5′-diphosphoribose (ADPR), and nicotinamide adenine dinucleotide (NAD), directly activated LTRPC2, which functioned as a Ca 2+ -permeable nonselective cation channel and enabled Ca 2+ influx into cells. This activation was suppressed by intracellular adenosine triphosphate. These results reveal that ADPR and NAD act as intracellular messengers and may have an important role in Ca 2+ influx by activating LTRPC2 in immunocytes.
