To obtain clues to the normal biological role of DMPK in cellular ion homeostasis , we have compared the resting [ Ca2 + ] i , the amplitude and shape of depolarization-induced Ca2 + transients , and the content of ATP-driven ion pumps in cultured skeletal muscle cells of wild-type and DMPK [ -/- ] knockout mice .
