Mitochondrial outer membrane transport complex Sam37/metaxin, N-terminal domain (IPR019564)

Short name: Sam37/metaxin_N

Overlapping homologous superfamilies


Domain relationships



Sam37 (also known as TOM37) is a component of the mitochondrial outer membrane sorting assembly machinery (SAM or TOB) complex, which is required for the sorting of proteins with complicated topology, such as beta-barrel proteins, to the mitochondrial outer membrane after import by the TOM complex [PMID: 12891361]. It has homology with Metaxin-1, also part of the outer mitochondrial membrane beta-barrel protein transport complex [PMID: 17981999, PMID: 9045676].
