This is the N-terminal GTPase-binding domain (GBD) of formins also known as formin homology domain-containing proteins (FHOD). This GBD was initially described to be recruited by Rac and Ras GTPases in cells and to play play an essential role for FHOD1-mediated actin remodelling and transcriptional activation, localizes to specific GTPases in cells, and binds to GTPases in vitro. It exhibits structural similarity to the ubiquitin superfold as found, for example, in the Ras-binding domains of c-Raf1 or PI3 kinase, but contains an unusual loop that inserts into the first FH3 repeat [1]. This domain has been described as a modulator of the binding specificity of the neighboring FH3 domain, making the paired domain specific for spectrin repeats rather than GTPase interaction [2].
