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}.
