Drf_GBD

Diaphanous GTPase-binding Domain
Drf_GBD
SMART accession number:SM01140
Description: This domain is bound to by GTP-attached Rho proteins, leading to activation of the Drf protein.
Interpro abstract (IPR010473):

Diaphanous-related formins (Drfs) are a family of formin homology (FH) proteins that act as effectors of Rho small GTPases during growth factor-induced cytoskeletal remodelling, stress fibre formation, and cell division [ (PUBMED:10631086) ]. Drf proteins are characterised by a variety of shared domains: an N-terminal GTPase-binding domain (GBD), formin-homology domains FH1, FH2 ( IPR015425 ) and FH3 ( IPR010472 ), and a C-terminal conserved Dia-autoregulatory domain (DAD) that binds the GBD.

This entry represents the GBD, which is a bifunctional autoinhibitory domain that interacts with and is regulated by activated Rho family members. Mammalian Drf3 contains a CRIB-like motif within its GBD for binding to Cdc42, which is required for Cdc42 to activate and guide Drf3 towards the cell cortex where it remodels the actin skeleton [ (PUBMED:12676083) ].
