Mitochondrial import receptor subunit TOM22 homolog is a protein that in humans is encoded by the TOMM22 gene.^[3][4][5]

The protein encoded by this gene is an integral membrane protein of the mitochondrial outer membrane. The encoded protein interacts with TOMM20 and TOMM40, and forms a complex with several other proteins to import cytosolic preproteins into the mitochondrion.^[5]
