Description
Summary:Ubiquitin ligases are important regulators of nervous system development, function and disease. To date, numerous ubiquitin ligases have been discovered that regulate presynaptic biology. Here, we discuss recent findings on presynaptic ubiquitin ligases that include members from the three major ubiquitin ligase classes: RING, RBR and HECT. Several themes emerge based on findings across a range of model systems. A cadre of ubiquitin ligases is required presynaptically to orchestrate development and transmission at synapses. Multiple ubiquitin ligases deploy both enzymatic and non-enzymatic mechanisms, and act as hubs for signalling networks at the synapse. Both excitatory and inhibitory presynaptic terminals are influenced by ligase activity. Finally, there are several neurodevelopmental disorders and neurodegenerative diseases associated with presynaptic ubiquitin ligases. These findings highlight the growing prominence and biomedical relevance of the presynaptic ubiquitin ligase network.
