Common Name Somatostatin
Description Somatostatin is a peptide hormone that regulates the endocrine system and affects neurotransmission and cell proliferation via interaction with G protein-coupled somatostatin receptors and inhibition of the release of numerous secondary hormones. Somatostatin has two active forms produced by alternative cleavage of a single preproprotein: one of 14 amino acids, the other of 28 amino acids. In all vertebrates, there exists six different somatostatin genes that have been named SS1, SS2, SS3, SS4, SS5, and SS6 (PMID: 20472043 Link_out). The six different genes along with the five different somatostatin receptors allows somatostatin to possess a large range of functions. Humans have only one somatostatin gene, SST (PMID: 6126875 Link_out, 6142531 Link_out).
