TOM70 is the main receptor for the import of PINK1 into mitochondria. TOM20 plays only a minor role in PINK1 recognition at the organellar outer membrane. PINK1 association with the TOM complex is reduced upon knock-down of TOM7. The lumen of the TOM pore is crucial for PINK1 association with the outer membrane. TcPINK1 blocks the TOM pore in depolarized mitochondria.
