CC   -!- FUNCTION: Central component of the receptor complex responsible for the
CC       recognition and translocation of cytosolically synthesized
CC       mitochondrial preproteins. Together with TOM22 functions as the transit
CC       peptide receptor at the surface of the mitochondrion outer membrane and
CC       facilitates the movement of preproteins into the translocation pore (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Forms part of the preprotein translocase complex of the outer
CC       mitochondrial membrane (TOM complex). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion outer membrane {ECO:0000305};
CC       Single-pass membrane protein {ECO:0000305}.
CC   -!- INDUCTION: By salt-stress. {ECO:0000269|PubMed:18594887}.
CC   -!- MISCELLANEOUS: In mammals and fungi, the transmembrane domain is
CC       located at the N-terminus while it is located at the C-terminus in
CC       plants. The overall orientation of the protein in the membrane is
CC       therefore inverted.
CC   -!- SIMILARITY: Belongs to the Tom20 family. {ECO:0000305}.
