Cristae junctions are highly curved tubular openings that separate cristae membrane invaginations from the surrounding boundary membrane. Despite their central role in many vital cellular processes like apoptosis, the details of cristae junction formation remain elusive. Here we identify Mic10, a core subunit of the recently discovered MICOS complex, as an inner mitochondrial membrane protein with the ability to change membrane morphology in vitro and in vivo. We show that Mic10 spans the inner membrane in a hairpin topology and that its ability to sculpt membranes depends on oligomerization through a glycine-rich motif. Oligomerization mutants fail to induce curvature in model membranes, and when expressed in yeast, mitochondria display an altered inner membrane architecture characterized by drastically decreased numbers of cristae junctions. Thus, we demonstrate that membrane sculpting by Mic10 is essential for cristae junction formation."],["dc.identifier.doi","10.1016/j.cmet.2015.04.006"],["dc.identifier.gro","3141906"],["dc.identifier.isi","000353978700017"],["dc.identifier.pmid","25955211"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/2389"],["dc.language.iso","en"],["dc.notes.intern","WoS Import 2017-03-10"],["dc.notes.status","final"],["dc.notes.submitter","PUB_WoS_Import"],["dc.relation.eissn","1932-7420"],["dc.relation.issn","1550-4131"],["dc.relation.orgunit","Institut für Zellbiochemie"],["dc.title","Mic10 Oligomerizes to Bend Mitochondrial Inner Membranes at Cristae Junctions"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]

Both domains are connected by narrow, tubular membrane segments called cristae junctions (CJs). The formation and maintenance of CJs is of vital importance for the organization of the mitochondrial IM and for mitochondrial and cellular physiology. The multisubunit mitochondrial contact site and cristae organizing system (MICOS) was found to be a major factor in CJ formation. In this study, we show that the MICOS core component Mic60 actively bends membranes and, when inserted into prokaryotic membranes, induces the formation of cristae-like plasma membrane invaginations. The intermembrane space domain of Mic60 has a lipid-binding capacity and induces membrane curvature even in the absence of the transmembrane helix. Mic60 homologues from α-proteobacteria display the same membrane deforming activity and are able to partially overcome the deletion of Mic60 in eukaryotic cells. Our results show that membrane bending by Mic60 is an ancient mechanism, important for cristae formation, and had already evolved before α-proteobacteria developed into mitochondria."],["dc.identifier.doi","10.1083/jcb.201609046"],["dc.identifier.pmid","28254827"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/11711"],["dc.identifier.url","https://sfb1190.med.uni-goettingen.de/production/literature/publications/9"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.relation","SFB 1190: Transportmaschinen und Kontaktstellen zellulärer Kompartimente"],["dc.relation","SFB 1190 | P01: Untersuchung der Unterschiede in der Zusammensetzung, Funktion und Position von individuellen MICOS Komplexen in einzelnen Säugerzellen"],["dc.relation","SFB 1190 | P12: Funktionelle Regulation der mitochondrialen Präsequenz-Translokase"],["dc.relation.eissn","1540-8140"],["dc.relation.orgunit","Institut für Zellbiochemie"],["dc.relation.workinggroup","RG Jakobs (Structure and Dynamics of Mitochondria)"],["dc.relation.workinggroup","RG Meinecke (Molecular Membrane Biology)"],["dc.rights","CC BY-NC-SA 4.0"],["dc.title","The MICOS component Mic60 displays a conserved membrane-bending activity that is necessary for normal cristae morphology"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
