External Ids for HTR1B Gene
The neurotransmitter serotonin (5-hydroxytryptamine; 5-HT) exerts a wide variety of physiologic functions through a multiplicity of receptors and may be involved in human neuropsychiatric disorders such as anxiety, depression, or migraine. These receptors consist of several main groups subdivided into several distinct subtypes on the basis of their pharmacologic characteristics, coupling to intracellular second messengers, and distribution within the nervous system (Zifa and Fillion, 1992 [PubMed 1359584]). The serotonergic receptors belong to the multigene family of receptors coupled to guanine nucleotide-binding proteins.[supplied by OMIM, Oct 2009]
GeneCards Summary for HTR1B Gene
HTR1B (5-Hydroxytryptamine (Serotonin) Receptor 1B, G Protein-Coupled) is a Protein Coding gene. Diseases associated with HTR1B include intermittent explosive disorder and premature ejaculation. Among its related pathways are Signaling by GPCR and CREB Pathway. GO annotations related to this gene include drug binding and serotonin binding. An important paralog of this gene is HTR1F.
UniProtKB/Swiss-Prot for HTR1B Gene
G-protein coupled receptor for 5-hydroxytryptamine (serotonin). Also functions as a receptor for ergot alkaloid derivatives, various anxiolytic and antidepressant drugs and other psychoactive substances, such as lysergic acid diethylamide (LSD). Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of down-stream effectors, such as adenylate cyclase. Signaling inhibits adenylate cyclase activity. Arrestin family members inhibit signaling via G proteins and mediate activation of alternative signaling pathways. Regulates the release of 5-hydroxytryptamine, dopamine and acetylcholine in the brain, and thereby affects neural activity, nociceptive processing, pain perception, mood and behavior. Besides, plays a role in vasoconstriction of cerebral arteries.
Serotonin 5-HT1B receptors, previously known as 5-HT1D receptors, are primarily located in the basal ganglia, striatum, hippocampus and vascular smooth muscle. 5-HT1B receptors play a role in thermoregulation, respiration, appetite control, sexual behavior, aggression, and anxiety. The human 5-HT1B receptor gene has been localized to chromosome 6 (6q13).
