Summary: Predicted to enable guanyl-nucleotide exchange factor activity; microtubule binding activity; and small GTPase binding activity. Predicted to be involved in several processes, including cytoskeleton organization; positive regulation of macromolecule metabolic process; and regulation of signal transduction. Predicted to act upstream of or within negative regulation of podosome assembly. Is active in glutamatergic synapse and postsynaptic density, intracellular component. Human ortholog(s) of this gene implicated in neurodevelopmental disorder with midbrain and hindbrain malformations. Orthologous to human ARHGEF2 (Rho/Rac guanine nucleotide exchange factor 2).

Results indicated that Tau produced strong plasma membrane blebbing and F-Actin cytoskeleton remodeling by indirect activation of the GEF-H1-RhoA-ROCK pathway. All of these actions were initiated by abnormal, induced microtubule bundling and cytoplasmic release of GEF-H1.
Title: Expression of Tau Produces Aberrant Plasma Membrane Blebbing in Glial Cells Through RhoA-ROCK-Dependent F-Actin Remodeling.
regulation of c-Src trafficking requires both microtubules and actin polymerization, and GEF-H1 coordinates c-Src trafficking, acting as a molecular switch between these two mechanisms
Title: Microtubule and Actin Interplay Drive Intracellular c-Src Trafficking.
upregulation of GEF-H1 activity may contribute to excitotoxicity, whereas the late upregulation of GEF-H1 protein may promote neuroplasticity after brain ischemia.
Title: Upregulation of the GEF-H1 pathway after transient cerebral ischemia.
GEF-H1 activates RhoA in response to RalA GTPase, which in turn regulates the localization and the assembly of exocyst components and exocytosis.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
