KCNE1 potassium voltage-gated channel subfamily E regulatory subunit 1

Gene ID: 3753, updated on 11-Apr-2024
Gene type: protein coding
Also known as: ISK; JLNS; LQT5; MinK; JLNS2; LQT2/5

Summary

The product of this gene belongs to the potassium channel KCNE family. Potassium ion channels are essential to many cellular functions and show a high degree of diversity, varying in their electrophysiologic and pharmacologic properties. This gene encodes a transmembrane protein known to associate with the product of the KVLQT1 gene to form the delayed rectifier potassium channel. Mutation in this gene are associated with both Jervell and Lange-Nielsen and Romano-Ward forms of long-QT syndrome. Alternatively spliced transcript variants encoding the same protein have been identified. [provided by RefSeq, Jul 2008]
