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

This domain has been annotated as Rac1-binding domain [1, 2]. It can be found in human CYRIA/CYRIB and at the N terminus of CYFIP1/2 [3]. CYFIP proteins are known RAC1 effectors that stimulate actin polymerization [3]. In mice, CYRIB (also known as CYRI or FAM49B) negatively regulates RAC1-driven cytoskeletal remodelling and plays a role in restricting infection mediated by Mycobacterium tuberculosis and Listeria monocytogenes [3].
