Somatostatin receptor type 5 is a protein that in humans is encoded by the SSTR5 gene. [5]
Somatostatin acts at many sites to inhibit the release of many hormones and other secretory proteins. The biological effects of somatostatin are probably mediated by a family of G protein-coupled receptors that are expressed in a tissue-specific manner. SSTR5 is a member of the superfamily of receptors having seven transmembrane segments. [6]
Somatostatin, also known as growth hormone-inhibiting hormone (GHIH) or by several other names, 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 inhibits insulin and glucagon secretion.
Precortistatin is a protein that in humans is encoded by the CORT gene. The 105 amino acid residue human precortistatin in turn is cleaved into cortistatin-17 and cortistatin-29. Cortistatin-17 is the only active peptide derived from the precursor. Cortistatin is a neuropeptide that is expressed in inhibitory neurons of the cerebral cortex, and which has a strong structural similarity to somatostatin. Unlike somatostatin, when infused into the brain, it enhances slow-wave sleep. It binds to sites in the cortex, hippocampus and the amygdala.
The gastrin-releasing peptide receptor (GRPR), now properly known as BB2 is a G protein-coupled receptor whose endogenous ligand is gastrin releasing peptide. In humans it is highly expressed in the pancreas and is also expressed in the stomach, adrenal cortex and brain.
The prolactin-releasing peptide receptor (PrRPR) also known as G-protein coupled receptor 10 (GPR10) is a protein that in humans is encoded by the PRLHR gene.
Somatostatin receptor type 2 is a protein that in humans is encoded by the SSTR2 gene.
P2Y purinoceptor 2 is a protein that in humans is encoded by the P2RY2 gene.
Bradykinin receptor B1 (B1) is a G-protein coupled receptor encoded by the BDKRB1 gene in humans. Its principal ligand is bradykinin, a 9 amino acid peptide generated in pathophysiologic conditions such as inflammation, trauma, burns, shock, and allergy. The B1 receptor is one of two of G protein-coupled receptors that have been found which bind bradykinin and mediate responses to these pathophysiologic conditions.
The alpha-1A adrenergic receptor, also known as ADRA1A, formerly known also as the alpha-1C adrenergic receptor, is an alpha-1 adrenergic receptor, and also denotes the human gene encoding it. There is no longer a subtype α1C receptor. At one time, there was a subtype known as α1C, but it was found to be identical to the previously discovered α1A receptor subtype. To avoid confusion, the naming convention was continued with the letter D.
The alpha-1B adrenergic receptor (α1B-adrenoreceptor), also known as ADRA1B, is an alpha-1 adrenergic receptor, and also denotes the human gene encoding it. The crystal structure of the α1B-adrenergic receptor has been determined in complex with the inverse agonist (+)-cyclazosin.
The alpha-1D adrenergic receptor, also known as ADRA1D, is an alpha-1 adrenergic receptor, and also denotes the human gene encoding it.
Neuropeptides B/W receptor 1, also known as NPBW1 and GPR7, is a human protein encoded by the NPBWR1 gene. As implied by its name, it and related gene NPBW2 are transmembranes protein that bind Neuropeptide B (NPB) and Neuropeptide W (NPW), both proteins expressed strongly in parts of the brain that regulate stress and fear including the extended amygdala and stria terminalis. When originally discovered in 1995, these receptors had no known ligands and were called GPR7 and GPR8, but at least three groups in the early 2000s independently identified their endogenous ligands, triggering the name change in 2005.
Neuropeptides B/W receptor 2, also known as NPBW2, is a human protein encoded by the NPBWR2 gene.
G-protein coupled receptor 39 is a protein that in humans is encoded by the GPR39 gene.
