• Function: The activity of this receptor is mediated by G proteins that stimulate adenylate cyclase. 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.
• KEGG Pathway:
  Calcium signaling pathway (hsa04020)
  cAMP signaling pathway (hsa04024)
  Neuroactive ligand-receptor interaction (hsa04080)
  Serotonergic synapse (hsa04726)
• Reactome Pathway:
  G alpha (s) signalling events (R-HSA-418555)
  Serotonin receptors (R-HSA-390666)
