Receptor for somatostatin-14. The activity of this receptor is mediated by G proteins which inhibits adenylyl cyclase. It is functionally coupled not only to inhibition of adenylate cyclase, but also to activation of both arachidonate release and mitogen-activated protein (MAP) kinase cascade. Brain, lung, heart and islets. Moderate levels in the hippocampus, cortex and olfactory bulb. Belongs to the G-protein coupled receptor 1 family.
