Somatostatin Receptor 1 (SSTR1) Antibody

Background

SSTR1 is a G protein-coupled receptor (GPCR) that binds somatostatin, a peptide hormone that inhibits the release of various other hormones, including growth hormone, insulin, and glucagon. SSTR1 is predominantly expressed in the brain, pancreas, and gastrointestinal tract. It primarily couples to Gi proteins, inhibiting adenylate cyclase activity and reducing cAMP levels, which leads to the suppression of hormone secretion and modulation of neurotransmitter release. In the central nervous system, SSTR1 regulates neurotransmission and has a role in inhibiting secretion of growth hormone from the pituitary. Dysregulation of SSTR1 signaling is implicated in disorders like acromegaly, diabetes, and certain neuroendocrine tumors, where excessive hormone secretion or abnormal growth occurs. SSTR1 agonists, such as octreotide, are used therapeutically to treat conditions such as acromegaly and neuroendocrine tumors by inhibiting growth hormone and other secretions.
