Somatostatin receptors are receptors for the ligand somatostatin, a small neuropeptide associated with neural signaling, particularly in the post-synaptic response to NMDA receptor co-stimulation/activation. Somatostatin is encoded by a CRE and is very susceptible to gene promoter region activation by transcription factor CREB.

There are five known somatostatin receptors:

• SST₁ (SSTR1)
• SST₂ (SSTR2)
• SST₃ (SSTR3)
• SST₄ (SSTR4)
• SST₅ (SSTR5)

All are G protein-coupled seven transmembrane receptors.
