Comments
| Comment Type | Description |
|---|---|
| Alternative Products | Event=Alternative splicing; Named isoforms=3; Comment=Additional isoforms seem to exist. Isoforms have identical ligand binding properties but different coupling properties with G proteins: isoform Alpha and isoform Beta couple to G(i) proteins, whereas isoform Gamma couples to multiple G proteins, G(i) and G(s).; Name=Alpha; IsoId=P34980-1; Sequence=Displayed; Name=Beta; IsoId=P34980-2; Sequence=VSP_001949; Name=Gamma; IsoId=P34980-3; Sequence=VSP_001950; |
| Function | Receptor for prostaglandin E2 (PGE2); the EP3 receptor may be involved in inhibition of gastric acid secretion, modulation of neurotransmitter release in central and peripheral neurons, inhibition of sodium and water reabsorption in kidney tubulus and contraction in uterine smooth muscle. The activity of this receptor can couple to both the inhibition of adenylate cyclase mediated by G(i) proteins, and to an elevation of intracellular calcium. The various forms can interact with different second messenger systems (By similarity) |
| Similarity | Belongs to the G-protein coupled receptor 1 family |
| Subcellular Location | Cell membrane; Multi-pass membrane protein. |
| Tissue Specificity | Principally expressed in the tubules of the renal medulla. Specific expression is seen in medullary and cortical thick ascending limbs; lower levels are detected in cortical and inner medullary collecting ducts. Not detected significantly in the glomeruli. In the brain, expressed in all types of glial cells. |
