MIRO domain (IPR020860)

Short name: MIRO_dom

Domain relationships


Mitochondrial Rho proteins (Miro-1, Q8IXI2 and Miro-2, Q8IXI1) are atypical Rho GTPases. They have a unique domain organisation, with tandem GTP-binding domains and two EF hand domains (IPR002048), that may bind calcium. They are also larger than classical small GTPases. It has been proposed that they are involved in mitochondrial homeostasis and apoptosis [PMID: 12482879].

This entry represents the tandemly repeated GTPase domain from these proteins.
