5-hydroxytryptamine receptor 1B (UniProt P28222; also known as 5-HT-1B, 5-HT-1D-beta, 5-HT1B, S12, Serotonin 1D beta receptor, Serotonin receptor 1B) is encoded by the HTR1B (also known as HTR1DB) gene (Gene ID 3351) in human. The 5-HT receptors are grouped according to their antagonist susceptibilities and their affinities for 5-HT. The 5-HT1 receptors are a subfamily of 5-HT receptors that were originally classified according to their inhibition of adenylyl cyclase, degree of sequence similarity and their overlapping pharmacological specificities. The subfamily has five different receptors: 5-HT1A, 5-HT1B, 5-HT1D, 5-HT1E, 5-HT1F that can couple to Gi/Go and mediate inhibitory neurotransmission. 5HT-1B receptor belong to the family of G-protein coupled receptors that are distributed in brain cortex, striatum, amygdala, medulla, hippocampus, caudate nucleus and putamen. 5-HT-1B also functions as a receptor for ergot alkaloid derivatives, various anxiolytic and antidepressant drugs and other psychoactive substances, such as lysergic acid diethylamide. Ligand binding causes a conformation change in the receptor that triggers signaling via G-proteins, which modulates the activity of down-stream effectors, such as adenylate cyclase. Signaling via 5-HT-1B inhibits adenylate cyclase activity. 5-HT1B receptor is known to be involved in thermoregulation, respiration, appetite control, sexual behavior, and aggression.5-HT-1B receptor are therapeutic targets for antimigraine drugs and for treatment of bipolar disorders, autism, and anti-aggressive agents.
