Rôles

Il joue un rôle important dans l'homéostasie des mitochondries^[5] en intervenant dans l'autophagie de ces dernières^[6]. Il intervient également dans l'intégrité de la chaîne de transport d'électrons^[7]. Il intervient ainsi dans plusieurs tissus, dont les neurones mais aussi le muscle cardiaque^[8] et le poumon, protégeant ce dernier de la fibrose pulmonaire^[9].

En médecine

La mutation du PINK1 est responsable d'une forme précoce et familiale de maladie de Parkinson^[10], appelée « maladie de Parkinson de type 6 » ou PARK6. La forme inactive du PINK1 entraîne une altération des mitochondries des neurones dopaminergiques et une concentration augmentée en dérivés réactifs de l'oxygène^[11] qui est délétère pour la cellule.
