Summary
Mitochondrial contact site complex
Mitofilin proteins are crucial organizers of mitochondrial architecture. They are located in the inner mitochondrial membrane and interact with several protein complexes of the outer membrane, thereby generating contact sites between the two membrane systems of mitochondria. They are part of hetero-oligomeric protein complexes that have been termed the mitochondrial inner membrane organizing system (MINOS), alternatively, mitochondrial organizing structure (MitOS) or mitochondrial contact site (MICOS) complex [1]. MICOS interacts with components of the sorting and assembly machinery (SAM) complex of the outer membrane to form the mitochondrial intermembrane space bridging (MIB) complex [2].
This clan contains 2 families and the total number of domains in the clan is 1063. The clan was built by S El-Gebali.
