Protein Structure
UniProt Annotation
Function Essential transmembrane GTPase, which mediates mitochondrial fusion. Fusion of mitochondria occurs in many cell types and constitutes an important step in mitochondria morphology, which is balanced between fusion and fission. MFN1 acts independently of the cytoskeleton. Overexpression induces the formation of mitochondrial networks. {ECO:0000269PubMed:11181170, ECO:0000269PubMed:12475957, ECO:0000269PubMed:12759376, ECO:0000269PubMed:23921378}.
Subcellular Localization Mitochondrion outer membrane {ECO:0000305PubMed:11751411, ECO:0000305PubMed:12759376}; Multi- pass membrane protein {ECO:0000305PubMed:11751411, ECO:0000305PubMed:12759376}.Isoform 2: Cytoplasm.
Disease Associations
Tissue Specificity Ubiquitous. Expressed at slightly higher level in kidney and heart. Isoform 2 may be overexpressed in some tumors, such as lung cancers. {ECO:0000269PubMed:11751411, ECO:0000269PubMed:11950885, ECO:0000269PubMed:12759376}.
