Roc, or Ras of Complex, proteins are mitochondrial Rho proteins (Miro-1, Swiss:Q8IXI2, and Miro-2, Swiss:Q8IXI1) and atypical Rho GTPases. Full-length proteins have a unique domain organisation, with tandem GTP-binding domains and two EF hand domains (Pfam:PF00036) 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 [1,2,3,4].	Domain
