CC -!- FUNCTION: G-protein coupled receptor for 5-hydroxytryptamine
CC (serotonin). Also functions as a receptor for various drugs and
CC psychoactive substances, including ergot alkaloid derivatives, 1-2,5,-
CC dimethoxy-4-iodophenyl-2-aminopropane (DOI) and lysergic acid
CC diethylamide (LSD). Ligand binding causes a conformation change that
CC triggers signaling via guanine nucleotide-binding proteins (G proteins)
CC and modulates the activity of down-stream effectors. Beta-arrestin
CC family members inhibit signaling via G proteins and mediate activation
CC of alternative signaling pathways. Signaling activates a
CC phosphatidylinositol-calcium second messenger system that modulates the
CC activity of phosphatidylinositol 3-kinase and down-stream signaling
CC cascades and promotes the release of Ca(2+) ions from intracellular
CC stores. Regulates neuronal activity via the activation of short
CC transient receptor potential calcium channels in the brain, and thereby
CC modulates the activation of pro-opiomelacortin neurons and the release
CC of CRH that then regulates the release of corticosterone. Plays a role
CC in the regulation of appetite and feeding behavior, responses to
CC anxiogenic stimuli and stress. Plays a role in insulin sensitivity and
CC glucose homeostasis (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Interacts with MPDZ. Interacts with ARRB2 (By similarity).
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Multi-pass membrane
CC protein {ECO:0000250}.
CC -!- DOMAIN: The PDZ domain-binding motif is involved in the interaction
CC with MPDZ. {ECO:0000250}.
CC -!- PTM: N-glycosylated. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the G-protein coupled receptor 1 family.
CC {ECO:0000255|PROSITE-ProRule:PRU00521}.
