Function

[MCF2L_RAT] Guanine nucleotide exchange factor that potentially links pathways that signal through RAC1, RHOA and CDC42. Catalyzes guanine nucleotide exchange on RHOA and CDC42 and interacts specifically with the GTP-bound form of RAC1, suggesting that it functions as an effector of RAC1. May also participate in axonal transport in the brain. Becomes activated and highly tumorigenic by truncation of the N-terminus.

Publication Abstract from PubMed

Dbl proteins are guanine nucleotide exchange factors for Rho GTPases, containing adjacent Dbl homology (DH) and pleckstrin homology (PH) domains. This domain architecture is virtually invariant and typically required for full exchange potential. Several structures of DH/PH fragments bound to GTPases implicate the PH domain in nucleotide exchange. To more fully understand the functional linkage between DH and PH domains, we have determined the crystal structure of the DH/PH fragment of Dbs without bound GTPase. This structure is generally similar to previously determined structures of Dbs bound to GTPases albeit with greater apparent mobility between the DH and PH domains. These comparisons suggest that the DH and PH domains of Dbs are spatially primed for binding GTPases and small alterations in intradomain conformations that may be elicited by subtle biological responses, such as altered phosphoinositide levels, are sufficient to enhance exchange by facilitating interactions between the PH domain and GTPases.
