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].

PF09632Rac1-binding domain (Rac1)Rac1-binding domainThe Rac1-binding domain is the C-terminal portion of YpkA from Yersinia.

It is an all-helical molecule consisting of two distinct subdomains connected by a linker. the N-terminal end, residues 434-615, consists of six helices organised into two three-helix bundles packed against each other. This region is involved with binding to GTPases. The C-terminal end, residues 705-732. is a novel and elongated fold consisting of four helices clustered into two pairs, and this fold carries the helix implicated in actin activation. Rac1-binding domain mimics host guanidine nucleotide dissociation inhibitors (GDIs) of the Rho GTPases, thereby inhibiting nucleotide exchange in Rac1 and causing cytoskeletal disruption in the host [1]. It is usually found downstream of Pfam:PF00069.
