Previous GeneCards Identifiers for RGS18 Gene
This gene encodes a member of the regulator of G-protein signaling family. This protein is contains a conserved, 120 amino acid motif called the RGS domain. The protein attenuates the signaling activity of G-proteins by binding to activated, GTP-bound G alpha subunits and acting as a GTPase activating protein (GAP), increasing the rate of conversion of the GTP to GDP. This hydrolysis allows the G alpha subunits to bind G beta/gamma subunit heterodimers, forming inactive G-protein heterotrimers, thereby terminating the signal. Alternate transcriptional splice variants of this gene have been observed but have not been thoroughly characterized. [provided by RefSeq, Jul 2008]
GeneCards Summary for RGS18 Gene
RGS18 (Regulator Of G-Protein Signaling 18) is a Protein Coding gene. Among its related pathways are Signaling by GPCR and Interleukin receptor SHC signaling. GO annotations related to this gene include GTPase activator activity. An important paralog of this gene is RGS3.
UniProtKB/Swiss-Prot for RGS18 Gene
Inhibits signal transduction by increasing the GTPase activity of G protein alpha subunits thereby driving them into their inactive GDP-bound form. Binds to G(i) alpha-1, G(i) alpha-2, G(i) alpha-3 and G(q) alpha.
