Summary
{"type": "root", "children": [{"type": "p", "children": [{"type": "t", "text": "\nMICOS13, also known as QIL1, is a conserved core subunit of the mitochondrial contact site and cristae organizing system (MICOS) that is essential for maintaining the structural integrity of the mitochondrial inner membrane. By facilitating the formation of crista junctions, MICOS13 promotes the proper assembly of the MICOS complex, notably by integrating critical subunits such as MIC10, MIC26, and MIC27, while a MIC60/MIC19/MIC25 subcomplex persists independently yet remains insufficient for junction formation. Loss or depletion of MICOS13 leads to MICOS disassembly, aberrant cristae morphology, impaired respiratory function, and increased mitochondrial fragmentation in both cultured cells and animal models."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nFurthermore, mutations or targeted deletion of MICOS13 have been directly linked to severe mitochondrial pathologies, including early‐onset fatal mitochondrial encephalopathy, liver disease, and neurodegenerative disorders, where MICOS disassembly underlies disrupted cristae organization and respiratory chain dysfunction. Detailed structure–function studies have mapped critical domains within MICOS13—including a conserved N‐terminal GxxxG motif required for membrane insertion and an internal WN motif essential for maintaining protein stability and bridging the MICOS subcomplexes—thus underscoring its central role in both the maintenance of mitochondrial ultrastructure and the pathogenesis of mitochondrial disease."}, {"type": "fg", "children": [{"type": "fg_fs", "start_ref": "3", "end_ref": "5"}]}, {"type": "t", "text": "\n"}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "Virginia Guarani, Elizabeth M McNeill, Joao A Paulo, et al.
