Interactions in Neurodegenerative Disorders

1. What is Alpha-Synuclein?

Alpha-Synuclein is a 14-19 kDa phosphoprotein primarily localized in the presynaptic terminals of mature neurons, where it is involved in synaptic function and plasticity.

2. Why is Alpha-Synuclein important?

  • Alpha-Synuclein was the first missense mutation identified as a cause of familial Parkinson’s disease.

  • Aggregated and hyper-phosphorylated forms of Alpha-Synuclein are the major components of Lewy bodies.

  • Alpha-Synuclein is involved in regulation of the dopaminergic pathway.

  • Alpha-Synuclein reduces neuronal responsiveness to various apoptotic stimuli, leading to decreased caspase-3 activation.

  • Alpha-Synuclein intermediate oligomers/protofibrils are thought to be the major neurotoxic species.

  • Alpha-Synuclein is a target for the treatment of Parkinson’s disease; a humanized monoclonal anti-Alpha-Synuclein (PRX002) is currently under Phase 1 trails.
