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. {ECO:0000269|PubMed:11080193,
CC ECO:0000269|PubMed:17543467, ECO:0000269|PubMed:18599790,
CC ECO:0000269|PubMed:21508226, ECO:0000269|PubMed:8254366,
CC ECO:0000269|PubMed:9826725}.
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:0000269|PubMed:8254366};
CC Multi-pass membrane protein {ECO:0000269|PubMed:8254366}. Cell
CC projection, dendrite {ECO:0000250|UniProtKB:P19327}.
CC -!- TISSUE SPECIFICITY: Most abundantly expressed in midbrain, in dorsal
CC raphe and hippocampus. Detected at lower levels in amygdala and brain
CC cortex. {ECO:0000269|PubMed:9826725}.
CC -!- DISRUPTION PHENOTYPE: Mutant mice display decreased exploratory
CC behavior and increased fear-related behavior in anxiogenic
CC environments. Mutant mice display altered monoamine metabolism in
CC specific parts of the brain, especially in dorsal and medial raphe
CC nuclei, thalamus and hypothalamus, leading to altered levels of 5-
CC hydroxytryptamine, dopamine and their metabolites, as well as altered
CC noradrenaline levels. {ECO:0000269|PubMed:11080193,
CC ECO:0000269|PubMed:17543467, ECO:0000269|PubMed:9826725}.
CC -!- SIMILARITY: Belongs to the G-protein coupled receptor 1 family. 5-
CC hydroxytryptamine receptor subfamily. HTR1A sub-subfamily.
