These proteins share a DOCK-type C2 domain (also termed the DOCK-homology region (DHR)-1) at the N-terminal, and the DHR-2 domain (also termed the DOCKER domain) at the C-terminal. DHR-2 is the GEF catalytic domain organised into three lobes A, B and C, with the Rho-family binding site and catalytic centre generated entirely from lobes B and C. This entry represents Lobe B which adopts an unusual architecture of two antiparallel beta sheets disposed in a loosely packed orthogonal arrangement. This lobe changes its position relative to lobe C and the bound GTPase, which suggests that lobe B distinguishes between the switch 1 conformations of Rac1 and Cdc42 [2].

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].
