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 particular RNA sequence in human Kv1.1 and related genes triggers the precise conversion of adenosine to inosine through ADAR activity, playing a crucial role in gene expression.
