Gene Snapshot
5-hydroxytryptamine (serotonin) receptor 1B is a 5-hydroxytryptamine (serotonin) GPCR that belongs to the Class A GPCR family. They bind and transmit the signal from the neurotransmitter 5-HT (serotonin). The family can be subdivided into several subclasses based on pharmacology, signal transduction and structure. There are 5 serotonin receptors in the Drosophila melanogaster genome: 5-HT1A, 5-HT1B, 5-HT2A, 5-HT2B, and 5-HT7. [Date last reviewed: 2016-06-23]

5-HYDROXYTRYPTAMINE (SEROTONIN) GPCRs -
5-hydroxytryptamine (serotonin) GPCRs belong to the Class A GPCR family. They bind and transmit the signal from the neurotransmitter 5-HT (serotonin). The family can be subdivided into seven subclasses: 5-HT1-7 based on pharmacology, signal transduction and structure. (Adapted from PMID:18571247).
UniProt Contributed Function Data
This is one of the several different receptors for 5-hydroxytryptamine (serotonin), a biogenic hormone that functions as a neurotransmitter, a hormone, and a mitogen. The activity of this receptor is mediated by G proteins which inhibit adenylate cyclase.

Additional Descriptive Data
5-HT1B transcripts are detected throughout development with a peak in 16-24hr embryos. They are found in adult heads but not bodies. In embryos, expression starts in stage 16 and is restricted to the CNS. 5-HT1B transcripts are expressed in lateral rows of cells on each side of the midline and at a low level in midline cells.

      New annotation (CG30126) in release 3 of the genome annotation.
      5-HT1B receptor inhibits adenylate cyclase and activates phospholipase C. Expression starts in late embryos and is restricted to distinct populations in the CNS. 5-HT1A and 5-HT1B have a common chromosomal location and high sequence homology suggesting they are the result of a recent duplication event.
      One of several known Drosophila serotonin receptor encoding genes. Presumed to be a recent duplication of 5-HT1A gene.
