Able to potentiate G(olf)-alpha-dependent cAMP accumulation suggesting that it may be an important component for odorant signal transduction. {ECO:0000250}. |Ric8| |G-protein alpha-subunit binding| |guanyl-nucleotide exchange factor activity| |cell cortex| |regulation of G protein-coupled receptor signaling pathway| |GTPase activator activity| |positive regulation of GTPase activity| |regulation of GTPase activity| |centrosome| |positive regulation of hydrolase activity| |regulation of hydrolase activity| |G protein-coupled receptor signaling pathway| |positive regulation of catalytic activity| |positive regulation of molecular function| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp241|QNZ 0.01μM R05 exp241]]|-1.88| |[[:results:exp489|Hippuristanol 0.12μM R08 exp489 no dilution day6]]|1.77| |[[:results:exp456|Benzoate 20000μM R08 exp456]]|1.91| |[[:results:exp180|Dynasore 10μM R04 exp180]]|2| No correlation found to any other genes in chemogenomics.
