Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables potassium channel regulator activity. Involved in potassium ion transmembrane transport; secretory granule organization; and vestibular nucleus development. Acts upstream of or within epithelial cell maturation; heart contraction; and regulation of heart rate by cardiac conduction. Is active in apical plasma membrane. Is expressed in several structures, including ear; embryo ectoderm; genitourinary system; great vessel of heart; and heart. Used to study Jervell-Lange Nielsen syndrome. Human ortholog(s) of this gene implicated in Jervell-Lange Nielsen syndrome; atrial fibrillation; long QT syndrome; and long QT syndrome 5. Orthologous to human KCNE1 (potassium voltage-gated channel subfamily E regulatory subunit 1).
