G protein-coupled adenosine receptor activity

Definition

Target type: molecularfunction

Combining with adenosine and transmitting the signal across the membrane by activating an associated G-protein; promotes the exchange of GDP for GTP on the alpha subunit of a heterotrimeric G-protein complex. [GOC:bf, GOC:mah, PMID:9755289]

G protein-coupled adenosine receptors (GPCRs) are cell surface receptors that bind adenosine, a nucleoside that plays a crucial role in various physiological processes. These receptors are characterized by their seven transmembrane domains, which span the cell membrane. Upon adenosine binding, GPCRs undergo conformational changes that activate intracellular signaling pathways. The molecular function of G protein-coupled adenosine receptor activity involves the following steps:

1. **Ligand Binding:** Adenosine binds to the extracellular domain of the GPCR, triggering a series of conformational changes within the receptor.

2. **G Protein Coupling:** The activated receptor interacts with a heterotrimeric G protein located on the intracellular side of the membrane. This interaction leads to the dissociation of the G protein alpha subunit from the beta and gamma subunits.

3. **Signal Transduction:** The activated G protein alpha subunit, which is now bound to GTP, diffuses along the inner leaflet of the plasma membrane and interacts with downstream effector proteins.

4. **Effector Activation:** Depending on the specific G protein subtype coupled to the receptor, downstream effectors can include adenylyl cyclase, phospholipase C, or ion channels.

5. **Second Messenger Production:** Activation of effectors can lead to the production of second messengers, such as cAMP or inositol triphosphate (IP3), which further amplify the intracellular signal.

6. **Cellular Responses:** The changes in intracellular signaling pathways initiated by GPCR activation result in a wide range of cellular responses, including modulation of ion channel activity, gene expression, and cell growth and differentiation.

7. **Desensitization:** Prolonged activation of GPCRs can lead to desensitization, a process that reduces the sensitivity of the receptor to further stimulation. Desensitization can occur through phosphorylation of the receptor by specific kinases, followed by the binding of arrestin proteins, which block the interaction of the receptor with G proteins.'

However, its usefulness is transient often because of rapid development of tolerance. Its antiepileptic effect may be due to its inhibitory effect on brain carbonic anhydrase, which leads to an increased transneuronal chloride gradient, increased chloride current, and increased inhibition.
