MiRP1 forms IKr potassium channels with HERG and is associated with cardiac arrhythmia. [PDF]
, 1999 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 ...

Potassium Channel Mechanics [PDF]
Neuron, 2001 What is the moving part that switches an ion channel's current on and off? In this issue of Neuron del Camino and Yellen (2001) exploit scanning cysteine mutagenesis and sulfhydryl reagents to show that the intracellular end of the S6 helices forms a mechanical gate for the Shaker potassium channel.
