NCIt definition : Somatostatin receptor type 5 (364 aa, 39 kDa) is encoded by the human SSTR5 gene.
This protein is involved in somatostatin-dependent G protein-coupled receptor signaling.;
NCIt note : Somatostatin receptor (SSTR) 5 and D2R GPCRs interact to create a novel receptor with
enhanced activity; either ligand promotes heterodimerization. SSTR5 increases DNA
synthesis, whereas SSTR2 inhibits DNA synthesis and cell proliferation. SSTR2 appears
to antagonize SSTR5, and vice versa, suggesting a tissue-specific function and interaction
between these receptors. SSTR5 is expressed in adult pituitary gland, heart, small
intestine, adrenal gland, cerebellum and fetal hypothalamus.(OMIM 182455 and SWISS-PROT
