The injection of tetraethylammonium chloride into the giant axon of the squid prolongs the action potential and eliminates most of the late current under voltage-clamp. Experiments on fibers in an external medium of high potassium ion concentration demonstrate that injected tetraethylammonium chloride causes rectification of the instantaneous current-voltage curve for potassium by excluding out...
Recently, we have isolated the rat (r) H(+)/organic cation antiporter multidrug and toxin extrusion 1 (MATE1) and reported its tissue distribution and transport characteristics. Functional characterization suggested that an oppositely directed H(+) gradient serves as a driving force for the transport of a prototypical organic cation, tetraethylammonium, by MATE1, but there is no direct evidence...
We investigated expression of the Na(+)-L-carnitine cotransport system and its role in transport of tetraethylammonium in a kidney epithelial cell line, LLC-PK(1). L-Carnitine uptake in the LLC-PK(1) cells was markedly stimulated in the presence of Na(+). The uptake was saturable, with Michaelis constant and maximal uptake velocity values of 7.8 microM and 153.7 pmol x mg protein(-1) x 15 min(-...
