The potassium channel RNA editing signal is an RNA element found in human Kv1.1 and its homologues which directs the efficient modification of an adenosine to inosine by an adenosine deaminase acting on RNA (ADAR).
A specific RNA sequence in human Kv1.1 and related genes serves as a signal, guiding the precise modification of adenosine to inosine through the action of ADAR.
