Somatostatin receptor

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)
