Phosphoglycerate kinase is a central leverage point in Parkinson's Disease driven neuronal metabolic deficits.

Phosphoglycerate kinase 1 (PGK1), the first ATP producing glycolytic enzyme, has emerged as a therapeutic target for Parkinson's Disease (PD), since a potential enhancer of its activity was reported to significantly lower PD risk. We carried out a suppressor screen of hypometabolic synaptic deficits and demonstrated that PGK1 is a rate limiting enzyme in nerve terminal ATP production. Increasing PGK1 expression in mid-brain dopamine neurons protected against hydroxy-dopamine driven striatal dopamine nerve terminal dysfunction
