ARHGEF18 (Rho Guanine Nucleotide Exchange Factor 18, 114kD Rho-specific Guanine Nucleotide Exchange Factor, p114-Rho-GEF, p114RhoGEF, Septin-associated RhoGEF, SA-RhoGEF, KIAA0521)
Description:
Acts as guanine nucleotide exchange factor (GEF) for RhoA GTPases. May play a role in actin cytoskeleton reorganization in different tissues since its activation induces formation of actin stress fibers. Also act as a GEF for RAC1, inducing production of reactive oxygen species (ROS). Does not act as a GEF for CDC42. The G protein beta-gamma (Gbetagamma) subunits of heterotrimeric G proteins act as activators, explaining the integrated effects of LPA and other G-protein coupled receptor agonists on actin stress fiber formation, cell shape change and ROS production.

Applications:
Suitable for use in ELISA, Western Blot, Immunoprecipitation, Immunocytochemistry and Immunofluorescence. Other applications not tested.

Recommended Dilution:
ELISA: 1:4000
Optimal dilutions to be determined by the researcher.

Storage and Stability:
