Human calmodulin mutations cause arrhythmia and affect neuronal function in C. elegans.

Abstract excerpt

In humans, mutations in calmodulin cause cardiac arrhythmia. These mutations disrupt the ability of calmodulin to sense calcium concentrations and correctly regulate two central calcium channels, together obstructing heart rhythm. This correlation is well established, but also surprising since calmodulin is expressed in all tissues and interacts with hundreds of proteins. Until now, most studies have focused on...
