Abstract
A single cation channel from Tetrahymena cilia was incorporated into planar lipid bilayers. This channel selected for K+, Na+ and Li+ over Cl- and gluconate-, and its single channel conductance (at +25 mV) was 211 .+-. 8 pS (mean .+-. SE)in 100 mM K+-gluconate. The channel was not voltage dependent and may contribute to the resting K+ conductance of ciliary membrane.This publication has 4 references indexed in Scilit:
