Somatostatin receptor 2a is highly evident in the cortex, but the somatostatin receptor 2b is not seen as much. The medulla oblongata shows equal amounts of the two variants being expressed. The Somatostatin receptor 2a was found mostly in far down layers of the cerebral cortex, in the human brain.

Glycoprotein IIb/IIIa inhibitors are frequently used during percutaneous coronary intervention (angioplasty with or without intracoronary stent placement).. They work by preventing platelet aggregation and thrombus formation.
2A peptides trigger the ribosome to skip peptide bond formation between the glycine (G) and proline (P) near the C-terminus of the 2A peptide, resulting in the peptide located upstream of the 2A peptide having extra amino acids appended to its C-terminus while the protein downstream the 2A peptide will have an extra proline on its N-terminus.
The 5-HT 2A receptor is a subtype of the 5-HT 2 receptor that belongs to the serotonin receptor family and is a G protein-coupled receptor (GPCR). [4] The 5-HT 2A receptor is a cell surface receptor, [5] but has several intracellular locations. [6] Like all 5-HT 2 receptors, the 5-HT 2A receptor is G q /G 11-protein coupled.

A crystal structure of the A 2A receptor bound with the agonist NECA and a G protein-mimic has been published in 2016 (PDB code: 5g53). [20] The encoded protein (the A 2A receptor) is abundant in basal ganglia, vasculature, T lymphocytes, and platelets and it is a major target of caffeine, which is a competitive antagonist of this protein. [21]
A 2A receptor antagonists may prevent hepatic cirrhosis, and pentoxifylline may inhibit phosphodiesterase and provide renal protection. [6]The A 2A receptor antagonists may be used for treatment of attention deficit hyperactivity disorder (), because of the receptors ability to regulate neurotransmission in the basal ganglia and cortex, particularly dopaminergic and glutamatergic signaling.
