RHOT1
Mitochondrial Rho GTPase 1 (MIRO1) is an enzyme that in humans is encoded by the ''RHOT1'' gene on chromosome 17.〔(【引用サイトリンク】 url = http://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=55288 )〕 As a Miro protein isoform, the protein facilitates mitochondrial transport by attaching the mitochondria to the motor/adaptor complex. Through its key role in mitochondrial transport, RHOT1 is involved in mitochondrial homeostasis and apoptosis, as well as Parkinson’s disease (PD) and cancer.〔 ==Structure== In mammals, RHOT1 is one of two Miro isoforms. Both isoforms share a structure consisting of two EF-hand motifs linking two GTP-binding domains and a C-terminal transmembrane domain that attaches the protein to the outer mitochondrial membrane (OMM).〔 The EF-hand motifs serve as binding sites for the adaptor protein Milton and the kinesin heavy chain. These domains can also bind calcium ions, and the binding results in a conformational change that dissociates the mitochondrial surface from kinesin.〔〔
