  • 功能：
    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.
  • 基因功能参考文献：
    1. Somatostatin receptor 5 variant (sst5TMD4) was expressed in a subset of breast cancers, where it correlated with angiogenic markers, lymphatic metastasis, and reduced disease-free survival. PMID: 27507050
    2. sst5TMD4 is overexpressed in PCa, especially in those patients with a worse prognosis, and plays an important pathophysiologic role in PCa, which suggesting its potential as a biomarker and/or therapeutic target PMID: 28705809
    3. In cotransfected HEK-293 cells, SSTR5 and CB1R existed in a constitutive heteromeric complex under basal condition, which was disrupted upon agonist treatments. Furthermore, concurrent receptor activation led to preferential formation of SSTR5 homodimer and dissociation of CB1R homodimer. PMID: 27984180
    4. A truncated splice variant of the somatostatin receptor subtype 5, is associated to features of increased aggressiveness in pancreatic neuroendocrine tumors. PMID: 26673010
    5. SSTR5 was the predominantly expressed receptor subtype in the cytoplasm of all GH-secreting adenomas tested, regardless of whether they came from octreotide-naive, octreotide-responsive, or octreotide-resistant patients. SSTR5 mRNA predominance was significant only in octreotide treated patients. Its expression was not correlated with baseline or post-octreotide GH or IGF-1 levels or tumor volume. PMID: 25008035

    15. SSTR5 P335L is a hypofunctional protein with a potentially harmful effect on function, as well as potential latent effect, and therefore it could affect the clinical response to somatostatin analog therapy for patients with pancreatic cancer. PMID: 21249361
    16. Our results demonstrate a previously undetected strong association of two SSTR5 single nucleotide polymorphisms with acromegaly PMID: 21810856
    17. ZDHHC5 and SSTR5 are colocalized at the plasma membrane and coexpression of ZDHHC5 increased palmitoylation of SSTR5 whereas knock-down of endogenous ZDHHC5 by siRNAs decreased it. PMID: 21820437
    18. differential gene expression profiles revealed more abundant mRNA expression in ectopic ACTH syndrome than in Cushing disease of SSTR-5 PMID: 21383526

    32. role for SSTR5 t-461c and c1004t alleles in influencing GH and IGF-I levels in patients with acromegaly, whereas SSTR2 and SSTR5 variants seem to have a minor role in determining the responsiveness to somatostatin analogs PMID: 15914528
