Protein: Mitochondrial import receptor subunit TOM40 homolog (Mitochondrial outer membrane protein of 38 kDa) (OM38) (Translocase of outer membrane 40 kDa subunit homolog) (Q75Q40)
Organism: Rattus norvegicus (Rat)
Function: Channel-forming protein essential for import of protein precursors into mitochondria. Plays a role in the assembly of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I) by forming a complex with BCAP31 and mediating the translocation of Complex I components from the cytosol to the mitochondria (By similarity).
Subcellular location: Mitochondrion outer membrane {ECO:0000250|UniProtKB:O96008}; Multi-pass membrane protein {ECO:0000255}. Note=Associates with the mitochondria-associated ER membrane via interaction with BCAP31. {ECO:0000250|UniProtKB:O96008}.
