Kcne2 - potassium voltage-gated channel subfamily E regulatory subunit 2

Enables several functions, including identical protein binding activity; transmembrane transporter binding activity; and voltage-gated potassium channel activity. Contributes to delayed rectifier potassium channel activity and inward rectifier potassium channel activity. Involved in several processes, including ion transmembrane transport; regulation of ion transmembrane transport; and tongue development. Located in several cellular components, including Golgi apparatus; cell surface; and endoplasmic reticulum. Is integral component of membrane. Part of voltage-gated potassium channel complex. Human ortholog(s) of this gene implicated in atrial fibrillation; familial atrial fibrillation; long QT syndrome; and long QT syndrome 6. Orthologous to human KCNE2 (potassium voltage-gated channel subfamily E regulatory subunit 2). [provided by Alliance of Genome Resources, Apr 2022]
