Abstract

Ubiquitination is a post-translational modification that can dynamically alter the function, degradation and transport of a protein, as well as its interaction with other proteins, and activity of an enzyme. Dysfunctional ubiquitination is detrimental to normal cellular functions, and can result in severe diseases. Over the last decade, although much research has focused on deciphering the role of the ubiquitination/ubiquitin proteasome system (UPS) in the onset and progression of various neurological disorders, the specific relationship between ubiquitination and various epilepsies has not been carefully reviewed. As an increasing amount of research has revealed the roles of ubiquitination in the trafficking of ion channels and the turn-over of synaptic receptors, it is crucial to take a deeper look into ubiquitination-associated epilepsy. Here, we review the role of ubiquitination in maintaining normal cellular activities in neurons and recent findings on the dysregulation of ubiquitination in epilepsy. We particularly focus on rare neurological disorders with comorbid epilepsy in the hope of drawing more attention to this area. Through categorizing epilepsy-associated E3 ubiquitin ligases and their substrates and discussing ubiquitination-related rare neurological disorders, we summarize where the field stands at the moment and what directions we should consider in the future.
