Summaries for ARHGEF18 Gene

Entrez Gene Summary for ARHGEF18 Gene

  • Rho GTPases are GTP binding proteins that regulate a wide spectrum of cellular functions. These cellular processes include cytoskeletal rearrangements, gene transcription, cell growth and motility. Activation of Rho GTPases is under the direct control of guanine nucleotide exchange factors (GEFs). The protein encoded by this gene is a guanine nucleotide exchange factor and belongs to the Rho GTPase GFE family. Family members share a common feature, a Dbl (DH) homology domain followed by a pleckstrin (PH) homology domain. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Oct 2008]

GeneCards Summary for ARHGEF18 Gene

ARHGEF18 (Rho/Rac Guanine Nucleotide Exchange Factor (GEF) 18) is a Protein Coding gene. Among its related pathways are Signaling by FGFR and Signaling by GPCR. GO annotations related to this gene include phospholipid binding and Rho guanyl-nucleotide exchange factor activity. An important paralog of this gene is ARHGEF11.

UniProtKB/Swiss-Prot for ARHGEF18 Gene

  • 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.
