CC -!- FUNCTION: G-protein coupled receptor for 5-hydroxytryptamine
CC (serotonin). Also functions as a receptor for various drugs 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. Beta-arrestin family members inhibit signaling via G
CC proteins and mediate activation of alternative signaling pathways.
CC Signaling inhibits adenylate cyclase activity and activates a
CC phosphatidylinositol-calcium second messenger system that regulates the
CC release of Ca(2+) ions from intracellular stores. Plays a role in the
CC regulation of 5-hydroxytryptamine release and in the regulation of
CC dopamine and 5-hydroxytryptamine metabolism. Plays a role in the
CC regulation of dopamine and 5-hydroxytryptamine levels in the brain, and
CC thereby affects neural activity, mood and behavior. Plays a role in the
CC response to anxiogenic stimuli (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Heterodimer; heterodimerizes with GPER1 (By similarity).
CC Interacts with YIF1B (By similarity). {ECO:0000250|UniProtKB:P08908,
CC ECO:0000250|UniProtKB:P19327}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:P19327};
CC Multi-pass membrane protein {ECO:0000250|UniProtKB:P19327}. Cell
CC projection, dendrite {ECO:0000250|UniProtKB:P19327}.
CC -!- SIMILARITY: Belongs to the G-protein coupled receptor 1 family. 5-
CC hydroxytryptamine receptor subfamily. HTR1A sub-subfamily.
CC {ECO:0000255|PROSITE-ProRule:PRU00521}.
