26123744 KCNE2 has been widely studied since its role in the heart was discovered; it is association with inherited and acquired human Long QT syndrome; physiological analyses together with genetics studies have uncovered a startling array of functions for KCNE2, in the heart, stomach, thyroid and choroid plexus. [Review]
24937480 Women with elevated BMI have enhanced hERG activity as a result of low beta-inhibitory protein expression, which likely contributes to weak contractions and poor labour outcomes.
24827085 The transmembrane domains (TMDs) of KCNE1 and KCNE2 were illustrated to associate with the KCNQ1 channel in different modes.
24796621 The effect of KCNE2 mutations on KV7.1 was abolished in the presence of the major IKs beta-subunit KCNE1, when coexpressed in a 1:1:1 molar ratio.
24631769 M54T MiRP1 mutation axecerbate drug-induced long QT syndrome and arrhythmia.
24460807 Mutations in KCNE2 has been shown to cause familial atrial fibrillation.
23890619 study concluded that the variants in KCNQ1, KCNH2, KCNE1 and KCNE2 genes may be correlated with the occurrence of part of sudden unexplained nocturnal death syndrome cases in southern China
23714088 Subjects with LQT-PM may have longer QTc intervals at rest and at peak exercise and all phases of the recovery period compared to controls. Those with homozygous SNPs (KCNE2 1%) had longer resting QTc intervals when compared to heterozygotes.
23504710 KCNE1 and KCNE2, auxiliary subunits of voltage-gated potassium channels, undergo sequential cleavage mediated by either alpha-secretase and presenilin(PS)/gamma-secretase or BACE1 and PS/gamma-secretase in cells.
23483772 Case Report: reduced expression of KCNE2 in surgically excised tissue from human gastric cancer associated with gastritis cystica profunda.
