KCNE1 and KCNE3 regulate K+ channel gating, voltage dependence and trafficking
KCNE1 and 3 often have opposite effects on channel function, especially so for KCNQ1
KCNE1-KCNQ1 channels are best known for their role in cardiomyocyte repolarization
KCNE3-KCNQ1 channels are important in various secretory epithelia
Human KCNE1 and KCNE3 sequence variants cause various cardiac arrhythmias
