"Mitochondrial membrane potential is reduced focally at a fission site by the Drp1 recruitment which is initiated by the interaction of Drp1 with mitochondrial zinc transporter Zip1 and Zn(2+) entry through the Zip1-MCU complex. After division healthy mitochondria restore MMP levels and participate in the fusion-fission cycle again but mitochondria that fail to restore MMP undergo mitophagy."xsd:string
