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].
Domain
PF00786P21-Rho-binding domain (PBD)P21-Rho-binding domainSmall domains that bind Cdc42p- and/or Rho-like small GTPases. Also known as the Cdc42/Rac interactive binding (CRIB).Domain
