Functional and Biochemical Characterization of KCNQ1/KCNE1 Subunit Interactions in the Cardiac IKs Potassium Channel
The IKs potassium channel, critical to control of heart electrical activity, requires assembly of pore-forming alpha subunits (KCNQ1) and accessory beta (KCNE1) subunits. IKs is the slowly activating component of delayed rectifier K+ current in the heart and is a major contributor to the timing of …
