  • 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. This receptor mediates its action by association with G proteins that activate a phosphatidylinositol-calcium second messenger system. This receptor is involved in tracheal smooth muscle contraction, bronchoconstriction, and control of aldosterone production.
  • Sequence similarities
    Belongs to the G-protein coupled receptor 1 family.
  • Domain
    The PDZ domain-binding motif is involved in the interaction with INADL, CASK, APBA1, DLG1 and DLG4.
  • Cellular localization
    Cell membrane. Localizes to the post-synaptic thickening of axo-dendritic synapses.
