Subcellular organization of UBE3A in neurons.

The Journal of comparative neurology | 2017

Ubiquitination regulates a broad array of cellular processes, and defective ubiquitination is implicated in several neurological disorders. Loss of the E3 ubiquitin-protein ligase UBE3A causes Angelman syndrome. Despite its clinical importance, the normal role of UBE3A in neurons is still unclear. As a step toward deciphering its possible functions, we performed high-resolution light and electron microscopic immunocytochemistry. We report a broad distribution of UBE3A in neurons, highlighted by concentrations in axon terminals and euchromatin-rich nuclear domains. Our findings suggest that UBE3A may act locally to regulate individual synapses while also mediating global, neuronwide influences through the regulation of gene transcription. J. Comp.
