General annotation (Comments)

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.

Subunit structure

Interacts with MPDZ and INADL. May interact with MPP3, PRDX6, DLG4, DLG1, CASK, APBA1 and MAGI2 By similarity.

Subcellular location

Cell membrane; Multi-pass membrane protein By similarity. Note: Localizes to the postsynaptic thickening of axo-dendritic synapses By similarity.

Domain

The PDZ domain-binding motif is involved in the interaction with INADL, CASK, APBA1, DLG1 and DLG4 By similarity.

Sequence similarities

Belongs to the G-protein coupled receptor 1 family.

Sequence caution

The sequence CAA32150.1 differs from that shown. Reason: Frameshift at position 37.
