{"symbol":"RGS21","synonyms":[],"name":"regulator of G-protein signaling 21","description":"Regulator of G protein signaling (RGS) proteins are regulatory and structural components of G protein-coupled receptor complexes. RGS proteins are GTPase-activating proteins for Gi (see GNAI1; MIM 139310) and Gq (see GNAQ; MIM 600998) class G-alpha proteins. They accelerate transit through the cycle of GTP binding and hydrolysis and thereby accelerate signaling kinetics and termination.[supplied by OMIM, Nov 2008]","ncbiEntrezGeneId":431704,"ncbiEntrezGeneUrl":"http://www.ncbi.nlm.nih.gov/gene/431704","proteins":[{"symbol":"RGS21_HUMAN","href":"/api/1.0/protein/RGS21_HUMAN"}],"hgncRootFamilies":[{"name":"Regulators of G-protein signaling (RGS)","href":"/api/1.0/gene_family/Regulators+of+G-protein+signaling+%28RGS%29"}]}
