[5][6][7][8] TOM20 is one of the receptor systems of the translocase of the outer membrane (TOM) complex in the outer mitochondrial membrane.

In mitochondrial protein import, TOM20 is closely associated with the pore-forming TOM40 complex and acts by recognizing and binding the N-terminal MTSs (matrix-targeting sequences), which form an amphipathic alpha helix and aid passage of the target proteins into the mitochondrial matrix.
