Maintenance of mitochondrial morphology protein 1 (IPR027537)

Short name: Mmm1

Overlapping homologous superfamilies


Family relationships



Maintenance of mitochondrial morphology protein 1 (Mmm1) is a component of the ERMES/MDM complex (composed of MMM1, MDM10, MDM12 and MDM34), which serves as a molecular tether to connect the endoplasmic reticulum and mitochondria. The MDM12-MMM1 subcomplex functions in biogenesis of all outer membrane beta-barrel proteins, and acts in a late step after the SAM (sorting and assembly machinery) complex [PMID: 17410204]. The MDM10-MDM12-MMM1 subcomplex further acts in the TOM40 (translocase of outer membrane 40)-specific pathway after the action of the MDM12-MMM1 complex [PMID: 8089172, PMID: 11266455, PMID: 19556461].
