A calcium-activated cation current by an alternatively spliced form of Trp3 in the heart.


To investigate a cDNA encoding cation current, we isolated an alternatively spliced form of a rat Trp3, designated Trp3sv. Trp3sv encodes 736 amino acids with a unique N terminus and six transmembrane segments. Expression of the cRNA in Xenopus oocytes was successfully performed. The cation selective current appeared after the addition of ionomycin or… (More)
