Mechanisms by which atrial fibrillation-associated mutations in the S1 domain of KCNQ1 slow deactivation of IKs channels.

The Journal of physiology - 1 Sept 2008

Restier Lioara, Cheng Lan, Sanguinetti Michael C

Abstract excerpt

The slow delayed rectifier K(+) current (I(Ks)) is a major determinant of action potential repolarization in the heart. I(Ks) channels are formed by coassembly of pore-forming KCNQ1 alpha-subunits and ancillary KCNE1 beta-subunits. Two gain of function mutations in KCNQ1 subunits (S140G and V141M...
