Mitochondrial fission factor (UniProt: Q9GZY8; also known as Mff) is encoded by the MFF (also known as C2orf33, AD030, AD033, GL004) gene (Gene ID: 56947) in human. Mff is a single-pass type IV membrane protein that is highly expressed in heart, kidney, liver, brain, muscle, and stomach. Mff is a homodimeric protein, but may also interact with other proteins. It plays a role in mitochondrial and peroxisomal fission and promotes the recruitment and association of the fission mediator dynamin-related protein 1 (DNM1L) to the mitochondrial surface. It is also suggested to be involved in regulation of synaptic vesicle membrane dynamics by recruitment of DNM1L to clathrin-containing vesicles. Mff has a cytoplasmic domain (aa 1-322), a helical domain (aa 323-340), and a mitochondrial intermembrane domain (aa 341-342). Mff is shown to be an essential factor for mitochondrial recruitment of Drp1 during mitochondrial fission in mammalian cells and its down-regulation inhibits mitochondrial recruitment of Drp1 and induces mitochondria elongation. Also, exogenous expression of Mff is shown to induce extensive mitochondrial fission. Mutations in MFF gene can cause a form of encephalopathy that is characterized by delayed psychomotor development, severe hypotonia with inability to walk, and microcephaly. (Ref.: Otera, H., et al.
