Polo-like-kinase-2-dependent α-Synuclein Serine-129 Phosphorylation: a Physiological RoleDuring Synaptic Activity

SUMMARY/ABSTRACT Parkinson’s disease (PD), dementia with Lewy bodies (DLB), multiple-system atrophy (MSA) and certain forms of Alzheimer’s disease (AD) are ‘synucleinopathies’ - brain diseases characterized by lesions (Lewy bod- ies/Lewy neurites) rich in α-synuclein (αS). Disease-modifying treatments are not available, in part due to a lack of insight into how native αS dynamics becomes aberrant. Our long-term goal is to understand αS biology in detail and to develop strategies to preserve/reestablish the normal physiological state and function of αS. αS in Lewy bodies/neurites is often phosphorylated on serine-129 (pS129), and the kinase(s) involved have been discussed as potential drug…
