Inhibitory effect of tartrate against phosphate-induced DJ-1 aggregation

The DJ-1 protein engages in diverse cellular and pathological processes, including tumorigenesis, apoptosis, sperm fertilization, and the progression of Parkinson's disease (PD). The functional dimeric form of DJ-1 transforms into non-functional filamentous aggregates in an inorganic phosphate (Pi)-dependent manner in vitro. Here, we demonstrated that Pi and reactive oxygen species (ROS) induce DJ-1 aggregation in Neuro2A and SH-SY5Y cells....
