Successful target
Disease [+] 1 Target-related Diseases +
1 Pituitary gland disorder [ICD-11: 5A60-5A61]
Functions as a receptor for various alkaloids and psychoactive substances. Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of down-stream effectors, such as adenylate cyclase. Signaling inhibits adenylate cyclase activity. G-protein coupled receptor for 5-hydroxytryptamine (serotonin).
