pfam08477: Roc (This model is not part of the current CDD release)
Ras of Complex, Roc, domain of DAPkinase
Roc, or Ras of Complex, proteins are mitochondrial Rho proteins (Miro-1 and Miro-2) and atypical Rho GTPases. Full-length proteins have a unique domain organisation, with tandem GTP-binding domains and two EF hand domains (pfam00036) 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.
