Includes sub-families Ras, Rab, Rac, Ral, Ran, Rap Ypt1 and more. Shares P-loop motif with GTP_EFTU, arf and myosin_head. See Pfam:PF00009 Pfam:PF00025, Pfam:PF00063. As regards Rab GTPases, these are important regulators of vesicle formation, motility and fusion. They share a fold in common with all Ras GTPases: this is a six-stranded beta-sheet surrounded by five alpha-helices [1].
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 ...
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].
