Abstract excerpt

1. Gating of the skeletal muscle chloride channel (ClC-1) is sensitive to extracellular pH. In this study, whole-cell recording of currents from wild-type (WT) ClC-1 and a mutant, R304E, expressed in the Sf-9 insect cell line was used to investigate further the nature of the pH-sensitive residues. 2. Extracellular Cd2+ produced a concentration-dependent block of WT ClC-1 with an IC50 of 1.0 +/- 0.1 mM and a Hill...
