      Background InformationRho guanine nucleotide exchange factor 2 (UniProt: Q92974; also known as Guanine nucleotide exchange factor H1, GEF-H1, Microtubule-regulated Rho-GEF, Proliferating cell nucleolar antigen p40) is encoded by the ARHGEF2 (also known as KIAA0651, LFP40) gene (Gene ID: 9181) in human. GEF-H1 is a microtubule-associated guanine nucleotide exchange factor (GEF) for the Rho family of small GTPases that activates Rho-GTPases by promoting the exchange of GDP for GTP. It localizes to the tips of cortical microtubules of the mitotic spindle during cell division and is released upon microtubule depolymerization. GEF-H1 is involved in epithelial barrier permeability, cell motility and polarization, dendritic spine morphology, antigen presentation, leukemic cell differentiation, cell cycle regulation, and innate immune response. GEF-H1 can act as an adaptor protein that links PP2A B subunits to KSR-1 and mediate the dephosphorylation of KSR-1 serine 392 and activate MAPK signaling. GEF-H1 I known to contributes to cell survival and growth in HRASV12- transformed cells and is reported to be essential for activation of MAP kinase pathway in response to HRASV12. It is also reported to be important for the growth and survival of HRASV12 transformed cells. GEF-H1 contains a DH (DBL-homology) domain (aa 235-432) that interacts with and promotes loading of GTP on RhoA and tyrosine phosphorylation of RIPK2. It also has two phorbol-ester/DAG-type zinc finger (aa 587-611) and the C-terminal coiled coil domains (aa 798-867), both of which are required for association with microtubules.
