2-Oxoglutarate receptor 1 (OXGR1), also known as cysteinyl leukotriene receptor E (CysLT_E) and GPR99,^[1] is a protein that in humans is encoded by the OXGR1 gene.^[2]^[3]^[4]

G protein-coupled receptors (GPCRs, or GPRs) contain 7 transmembrane domains and transduce extracellular signals through heterotrimeric G proteins.^[4]
