Identification of a COOH-terminal segment involved in maturation and stability of human ether-a-go-go-related gene potassium channels.

Abstract excerpt

Mutations in the potassium channel encoded by the human ether-a-go-go-related gene (HERG) have been linked to the congenital long QT syndrome (LQTS), a cardiac disease associated with an increased preponderance of ventricular arrhythmias and sudden death. The COOH terminus of HERG harbors a large number of LQTS mutations and its removal prevents functional expression for reasons that remain unknown. In this...
