CC -!- FUNCTION: G-protein coupled receptor for 5-hydroxytryptamine
CC (serotonin). Also functions as a receptor for various alkaloids and
CC psychoactive substances. Ligand binding causes a conformation change
CC that triggers signaling via guanine nucleotide-binding proteins (G
CC proteins) and modulates the activity of down-stream effectors, such as
CC adenylate cyclase. Signaling inhibits adenylate cyclase activity.
CC Arrestin family members inhibit signaling via G proteins and mediate
CC activation of alternative signaling pathways. Regulates the release of
CC 5-hydroxytryptamine, dopamine and acetylcholine in the brain, and
CC thereby affects neural activity, nociceptive processing, pain
CC perception, mood and behavior. Besides, plays a role in
CC vasoconstriction of cerebral arteries (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Homodimer. Heterodimer with HTR1D (By similarity).
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Multi-pass membrane
CC protein {ECO:0000250}.
CC -!- DOMAIN: Ligands are bound in a hydrophobic pocket formed by the
CC transmembrane helices. {ECO:0000250}.
CC -!- PTM: Phosphorylated. {ECO:0000250}.
CC -!- PTM: Palmitoylated. {ECO:0000250}.
CC -!- MISCELLANEOUS: A residue in the 7th transmembrane region ('Thr-355' in
CC human, 'Asn-351' in mouse and rat) is important for species-specific
CC sensitivity to various agonists. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the G-protein coupled receptor 1 family.
CC {ECO:0000255|PROSITE-ProRule:PRU00521}.
