General Information
Term G protein-coupled opsin signaling pathway ID (Ontology) GO:0016056 (Gene Ontology)
Definition A G protein-coupled receptor signaling pathway that starts with an opsin being activated by a photon, and ending with the light signal being trasmitted through the synapses. The signal can be transmitted via different Galpha subunits types: Go, Gs, Gq, and Gt.[ PubMed:19720651 PubMed:36272560 ]
Also Known As "G protein-mediated opsin signaling pathway" ; "rhodopsin mediated phototransduction" ; "rhodopsin mediated signalling pathway" (for all, see Synonyms field below)
