Summaries for SSTR1 Gene

Entrez Gene Summary for SSTR1 Gene

  • Somatostatins are peptide hormones that regulate diverse cellular functions such as neurotransmission, cell proliferation, and endocrine signaling as well as inhibiting the release of many hormones and other secretory proteins. Somatostatin has two active forms of 14 and 28 amino acids. The biological effects of somatostatins are mediated by a family of G-protein coupled somatostatin receptors that are expressed in a tissue-specific manner. The protein encoded by this gene is a member of the superfamily of somatostatin receptors having seven transmembrane segments. Somatostatin receptors form homodimers and heterodimers with other members of the superfamily as well as with other G-protein coupled receptors and receptor tyrosine kinases. This somatostatin receptor has greater affinity for somatostatin-14 than -28. [provided by RefSeq, Jul 2012]

GeneCards Summary for SSTR1 Gene

SSTR1 (Somatostatin Receptor 1) is a Protein Coding gene. Diseases associated with SSTR1 include pseudotumor cerebri and oncogenic osteomalacia. Among its related pathways are Signaling by GPCR and Signaling by GPCR. GO annotations related to this gene include somatostatin receptor activity. An important paralog of this gene is GALR2.

UniProtKB/Swiss-Prot for SSTR1 Gene

  • Receptor for somatostatin with higher affinity for somatostatin-14 than -28. This receptor is coupled via pertussis toxin sensitive G proteins to inhibition of adenylyl cyclase. In addition it stimulates phosphotyrosine phosphatase and Na(+)/H(+) exchanger via pertussis toxin insensitive G proteins

Tocris Summary for SSTR1 Gene

  • Voltage-gated sodium channels (NaV) are responsible for action potential initiation and propagation in excitable cells, including nerve, muscle, and neuroendocrine cell types. They are also expressed at low levels in non-excitable cells, where their physiological role is unclear. Structurally, Nav channels are composed of one pore-forming alpha-subunit, which may be associated with either one or more beta-subunits. alpha-subunits are composed for four homologous domains, each of which contains six transmembrane segments. The fourth transmembrane loop (S4) acts as the 'voltage sensor' and is activated by changes in membrane potential. S4 is also involved in channel gating.
