Evidence for Sequential Ion-binding Loci along the Inner Pore of the IRK1 Inward-rectifier K(+) Channel
Steep rectification in IRK1 (Kir2.1) inward-rectifier K(+) channels reflects strong voltage dependence (valence of ∼5) of channel block by intracellular cationic blockers such as the polyamine spermine. The observed voltage dependence primarily results from displacement, by spermine, of up to five K...
