General Information
Term Gi/o-coupled serotonin receptor activity ID (Ontology) GO:0001586 (Gene Ontology)
Definition Combining with serotonin and transmitting the signal across the membrane by activation of the Gi/o subunit of an associated cytoplasmic heterotrimeric G protein complex. The Gi/o subunit subsequently inhibits adenylate cyclase and results in a decrease in cyclic AMP (cAMP) levels.[ PubMed:18571247 ]
Also Known As"5-HT1 receptor activity" ; "serotonin receptor activity, coupled via Gi/o"
