May be involved in epithelial barrier permeability, cell motility and polarization, dendritic spine morphology, antigen presentation, leukemic cell differentiation, cell cycle regulation, innate immune response, and cancer. Binds Rac-GTPases, but does not seem to promote nucleotide exchange activity toward Rac-GTPases, which was uniquely reported in PubMed:9857026. May stimulate instead the cortical activity of Rac. Inactive toward CDC42, TC10, or Ras-GTPases. Forms an intracellular sensing system along with NOD1 for the detection of microbial effectors during cell invasion by pathogens. Required for RHOA and RIP2 dependent NF-kappaB signaling pathways activation upon S.flexneri cell invasion. Involved not only in sensing peptidoglycan (PGN)-derived muropeptides through NOD1 that is independent of its GEF activity, but also in the activation of NF-kappaB by Shigella effector proteins (IpgB2 and OspB) which requires its GEF activity and the activation of RhoA.

		+	== Publication Abstract from PubMed ==
		+	The guanine nucleotide exchange factor GEF-H1 (also known as ARHGEF2) is identified as a member of the Dbl family of GEFs. It regulates RhoA-dependent cell signaling pathways and plays important roles in biological processes. GEF-H1 contains an N-terminal zinc finger domain, a Dbl-homologous (DH) domain followed by a Pleckstrin homology (PH) domain, and a C-terminal domain. The specific roles of its PH domain are poorly understood. Here we report the crystal structure of human GEF-H1 PH domain to 2.45 A resolution. A conserved surface is formed by beta8, beta9, beta10, and it may mediate protein-protein interactions. Although the folding resembles other PH domains that have defined structures, superposition of different PH domains clearly shows that the loop between beta6/beta7 and the loop between beta3/beta4 are so close that they will prevent its binding with phosphoinositide due to steric hindrance, and this has been proved by isothermal titration calorimetry (ITC) and thermal shift assay (TSA). Our studies provide a structural framework for further work on the function of GEF-H1.
