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 C ...	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].
