The binding partners for MICOS in the outer membrane are Tom and SAM protein complexes, (involved in import of proteins into the mitochondria).

VDAC 

A multifunctional transmembrane channel protein (similar in structure to bacterial porins) allow passing of  ions and most small hydrophilic molecules (up to about 5000 Da).
