description | Mitochondrial Rho (Miro) proteins are aberrant members of the small GTPase superfamily found in most eukaryotes. Miro contains a transmembrane region located at the C terminus anchors the protein to the outer membrane of mitochondria, the GTPase domains and EF-hands located in the cytoplasm. Miro and its cytoplasmic binding partner Milton/TRAK link mitochondria to kinesin and dynein molecular motors in various cell types []. Mammals have two Miro orthologs , Miro1 and Miro2. They mediate mitochondrial trafficking in neurons by linking mitochondria to kinesin and dynein motor proteins for their transport in axons and dendrites [, ]. Yeasts have one Miro homologue, known as Gem1, which is part of the ERMES complex that links the ER to mitochondria []. Interestingly, ERMES is absent in metazoa []. |
