Somatostatin Receptor

Somatostatin Receptor

Somatostatin receptors (SSTR1, 2A and B, 3, 4 and 5) belong to the G protein coupled receptor family. Many human tumors, including the majority of neuroendocrine tumors, breast tumors, some brain tumors, renal cell tumors, lymphomas, and prostate cancer, express somatostatin receptors. By binding to somatostatin receptors, somatostatin produces cytotoxic and cytostatic effects as well as a general secretion-inhibiting effect.

While SSTR5 is selective for somatostatin-28, SSTRs 1-4 exhibit weak selectivity for somatostatin-14 binding. SSTRs 2, 3, and 5 belong to a similar somatostatin receptor subclass based on structural similarity and reactivity for octapeptide and hexapeptide somatostatin receptor analogs; SSTRs 1-4 react poorly with these analogs and belong to a different subclass. Through pertussis toxin-sensitive guanosine triphosphate (GTP)-binding proteins, the inhibition of adenylyl cyclase is functionally linked to all five somatostatin receptors. The mRNA for SSTRs 1–5 is widely expressed in the brain and other peripheral organs, and it shows an overlapping, distinctive pattern that is species- and tissue-specific as well as subtype-specific. SSTR2 and SSTR5 are expressed by all subsets of pituitary cells, with SSTR5 being more prevalent. Pituitary cells coexpress various subtypes of somatostatin receptors.
