EOG8B5RPB	GO:0005834	4/7	heterotrimeric G-protein complex	cellular_component	"Any of a family of heterotrimeric GTP-binding and hydrolyzing proteins; they belong to a superfamily of GTPases that includes monomeric proteins such as EF-Tu and RAS. Heterotrimeric G-proteins consist of three subunits; the alpha subunit contains the guanine nucleotide binding site and possesses GTPase activity; the beta and gamma subunits are tightly associated and function as a beta-gamma heterodimer; extrinsic plasma membrane proteins (cytoplasmic face) that function as a complex to transduce signals from G-protein coupled receptors to an effector protein."

EOG8B5RPB	GO:0004871	4/7	signal transducer activity	molecular_function	"Conveys a signal across a cell to trigger a change in cell function or state. A signal is a physical entity or change in state that is used to transfer information in order to trigger a response." [GOC:go_curators]
EOG8B5RPB	GO:0007186	4/7	G-protein coupled receptor signaling pathway	biological_process	"A series of molecular signals that proceeds with an activated receptor promoting the exchange of GDP for GTP on the alpha-subunit of an associated heterotrimeric G-protein complex. The GTP-bound activated alpha-G-protein then dissociates from the beta- and gamma-subunits to further transmit the signal within the cell. The pathway begins with receptor-ligand interaction, or for basal GPCR signaling the pathway begins with the receptor activating its G protein in the absence of an agonist, and ends with regulation of a downstream cellular process, e.g. transcription.  The pathway can start from the plasma membrane, Golgi or nuclear membrane (PMID:24568158 and PMID:16902576)." [GOC:bf, GOC:mah, PMID:16902576PMID\:24568158, Wikipedia:G_protein-coupled_receptor]
