mitochondrial fission 1 protein [Homo sapiens]

Protein Classification

mitochondrial fission 1 protein( domain architecture ID 10187549)

mitochondrial fission 1 (Fis1) protein is an essential protein in mediating mitochondrial fission, and is involved in the fragmentation of the mitochondrial network and its perinuclear clustering; contains tandem Tetratricopeptide repeat (TPR) motifs which are known to mediate protein-protein interactions

Mitochondrial Fission Protein Fis1, cytosolic domain; Fis1, along with Dnm1 and Mdv1, is an essential protein in mediating mitochondrial fission. Dnm1 and Fis1 are highly conserved, with a common mechanism in disparate species. In mutants of these proteins, mitochondrial fission is impaired, resulting in networks of undivided mitochondria. The Fis1 N-terminus is cytosolic and tethered to the mitochondrial outer membrane via a C-terminal transmembrane domain. Fis1 appears to act via the recruitment of division complexes to the mitochondrial outer membrane, via interactions with Mdv1 or Caf4. Fis1 has tandem Tetratricopeptide repeat (TPR) motifs which are known to mediate protein-protein interactions.
