Function

Receptor for somatostatin 28 and to a lesser extent for somatostatin-14. The activity of this receptor is mediated by G proteins which inhibit adenylyl cyclase. Increases cell growth inhibition activity of SSTR2 following heterodimerization.

Activity summary

Somatostatin Receptor 5 also known as SSTR5 is a G protein-coupled receptor with a molecular weight of approximately 61 kDa. Mechanically SSTR5 couples with G proteins to inhibit adenylyl cyclase activity leading to reduced cAMP levels. This receptor is expressed in different tissues including the brain pituitary gland and pancreas reflecting its diverse physiological roles. SSTR5 exhibits a distinct expression pattern compared to other somatostatin receptors providing a unique contribution to tissue-specific functions.

Biological function summary

The Somatostatin Receptor 5 regulates hormone secretion and cell proliferation. SSTR5 is not a part of a larger protein complex but it interacts with molecules such as somatostatin which is a peptide hormone that inhibits the release of several other hormones. Through these interactions SSTR5 helps control endocrine and exocrine secretions. Its role in modulating cell growth makes it an important factor in maintaining tissue homeostasis and influencing cell signaling processes.

Pathways

Somatostatin Receptor 5 is involved in the cAMP signaling pathway and the MAPK/ERK pathway. In the cAMP signaling pathway SSTR5 helps mediate the inhibitory effects on adenylyl cyclase while in the MAPK/ERK pathway it influences cell proliferation and differentiation. Related proteins in these pathways include other somatostatin receptors like SSTR2 with which SSTR5 might share regulatory effects on inhibitory processes. These pathways highlight the receptor's role in integrating multiple signaling cascades affecting both cellular metabolism and growth.

Associated diseases and disorders

Somatostatin Receptor 5 is associated with growth hormone-related disorders such as acromegaly and certain types of cancer like pancreatic cancer. In acromegaly SSTR5 alongside SSTR2 impacts the pathological overproduction of growth hormone due to its expression in pituitary adenomas. In pancreatic cancer an altered expression of SSTR5 can influence tumor progression due to its regulatory effects on cell proliferation pathways. Understanding SSTR5's interaction with these diseases helps in developing therapeutic strategies targeting its specific signaling functions.

    Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-Somatostatin Receptor 5 antibody [UMB4] (ab109495)

    Somatostatin receptor 2 (SSTR2), somatostatin receptor 5 (SSTR5) and CXCR4 expression in the hepatoblastoma cell line HepG2 and in the hepatoma cell lines Hep3B and HuH-7 in comparison to the small cell lung cancer cell line NCI-H69 and the neuroendocrine tumor cell line BON-1. Immunohistochemistry (red-brown color), counterstaining with hematoxylin; scale bar: 20 μm. Representative photomicrographs of three independent batches are shown.

    HepG2, Hep3B, HuH-7, NCI-H-69, and BON-1 cells (DSMZ, Braunschweig, Germany) were grown in 75 cm2 culture flasks to a confluency of 80%. Cells were washed once with phosphate-buffered saline and transferred into 10% buffered formalin (J.T.Baker, Deventer, The Netherlands) for 2 h. After centrifugation for 10 min at 3500 x g, the supernatant was removed, and 1 ml human pool plasma was added to the cell samples. After brief vortexing, 100 μl human fibrinogen (50–70% protein; ≥80% clottable) was added to each sample, and the samples were vortexed again. The resulting clots were placed for another 24 h in 10% buffered formalin and embedded in paraffin blocks.
