Succinate Receptor 1

The succinate receptor (SUCNR1, also known as GPR91) is a G protein-coupled receptor that is closely related to the family of P2Y purinoreceptors. The Succinate receptor was identified as being activated by physiological levels of the Kreb's cycle intermediate succinate and other dicarboxylic acids such as maleate. It is expressed in a variety of tissues, including blood cells, adipose tissue, the liver, retina, and kidney. In these tissues, this receptor and its ligand succinate have recently emerged as novel mediators in local stress situations, including ischemia, hypoxia, toxicity, and hyperglycemia. Amongst others, the succinate receptor is involved in recruitment of immune cells to transplanted tissues. Moreover, it was shown to play a key role in the development of diabetic retinopathy. However, most prominently, the role of locally increased succinate levels and succinate receptor activation in the kidney, stimulating the systemic and local renin–angiotensin system, starts to unfold: the succinate receptor is a key mediator in the development of hypertension and possibly fibrosis in diabetes mellitus and metabolic syndrome.
