Involvement of thiols in the induction of inward current induced by silver in frog skeletal muscle membrane.

T Aoki1, K Nihonyanagi, T Oba.   

Abstract

Exposure of voltage-clamped frog skeletal muscle fibres to silver caused a maintained inward current which could be carried by Ca2+, Mg2+ or Na+. Inorganic Ca2+ channel blockers and dithiothreitol (SH reducing agent) diminished this current, but a Na+ channel blocker did not. Thus, silver activates the Ca2+ channel by acting on SH groups in a Ca2+ channel protein.
