In this study, the authors show that overexpression/accumulation of the parkin substrate AIMP2 induces an age-dependent degeneration of dopaminergic neurons and results in motor dysfunction. This effect is dependent on AIMP2-induced activation of PARP1, which, in turn, induces cell death via parthanatos.
