Somatostatin acts as an inhibitor of hormonal secretion and cell proliferation by acting through 5 somatostatin receptors subtypes (sst1–5). Coupling with Gi/o proteins is associated with effects on various transduction pathways, as adenylate cyclase inhibition or phosphatases activation. Dopamine receptor subtype 2 (D2DR) acts through coupling with similar G-proteins and transduction pathways. Sst, mostly sst2 and sst5, are coexpressed with D2DR in many neuroendocrine no...
