  • 8065
Name 5-hydroxytryptamine receptor 1A
Synonyms
  1. 5-HT-1A
  2. 5-HT1A
  3. G-21
  4. Serotonin receptor 1A
Gene Name HTR1A
Protein Type Enzyme
Biological Properties
General Function Involved in G-protein coupled receptor protein signaling pathway
Specific Function 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 that inhibit adenylate cyclase activity
