Control of Channel Clustering by Cleavage

Enrichment of sodium channels at nodes of Ranvier, a hallmark of myelinated axons, underlies effective saltatory conduction. In this issue of Neuron, Eshed-Eisenbach et al. (2020) demonstrate that proteolysis of gliomedin, which drives initial channel clustering, provides a novel mechanism to ensure fidelity of channel localization to nodes.
