  ABSTRACT  
 
Activation of Rho-family GTPases involves the removal of bound GDP and the subsequent loading of GTP, all catalyzed by guanine nucleotide exchange factors (GEFs) of the Dbl-family. Despite high sequence conservation among Rho GTPases, Dbl proteins possess a wide spectrum of discriminatory potentials for Rho-family members. To rationalize this specificity, we have determined crystal structures of the conserved, catalytic fragments (Dbl and pleckstrin homology domains) of the exchange factors intersectin and Dbs in complex with their cognate GTPases, Cdc42 and RhoA, respectively. Structure-based mutagenesis of intersectin and Dbs reveals the key determinants responsible for promoting exchange activity in Cdc42, Rac1 and RhoA. These findings provide critical insight into the structural features necessary for the proper pairing of Dbl-exchange factors with Rho GTPases and now allow for the detailed manipulation of signaling pathways mediated by these oncoproteins in vivo.

The DH domain is yellow, and the PH domain is blue, with defined secondary structural elements labeled in accordance with described nomenclature^8. Cdc42 is green, except for the switch regions (s1 = residues 26 -40 and s2 = residues 57 -76), which are red. d, Ribbon diagram of the Dbs -RhoA complex. Coloring and labeling are equivalent to the ITSN -Cdc42 structure. All figures were prepared using SPOCK (http://quorum.tamu.edu/jon/spock/) or MOLSCRIPT36.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
