MiRP1 Forms IKr Potassium Channels with HERG and Is Associated with Cardiac Arrhythmia

A novel potassium channel gene has been cloned, characterized, and associated with cardiac arrhythmia. The gene encodes MinK-related peptide 1 (MiRP1), a small integral membrane subunit that assembles with HERG, a pore-forming protein, to alter its function. Unlike channels formed only with HERG, mi... View More
