Mechanism of Ba(2+) block of a mouse inwardly rectifying K(+) channel: differential contribution by two discrete residues

1. The block of the IRK1/Kir2.1 inwardly rectifying K(+) channel by a Ba(2+) ion is highly voltage dependent, where the ion binds approximately half-way within the membrane electrical field. The mechanism by which two distinct mutations, E125N and T141A, affect Ba(2+) block of Kir2.1 was investigate...
