DRFs (DIAPH1,2,3) are autoinhibited through intramolecular binding of a Diaphanous autoinhibitory domain to a conserved N-terminal regulatory element.
Autoinhibition is relieved through binding of the GTPase RhoA to the N-terminal element.

DRFs are regulated by a RhoGTPase-binding domain situated in the N-terminal region and a C-terminal Diaphanous-autoregulatory domain, whose interaction stabilises an autoinhibited inactive conformation.
