The Super Conserved Receptor Expressed in Brain (SREB) family are a group of related G-protein coupled receptors. Since no endogenous ligands have yet been identified for these receptors, they are classified as orphan receptors. Receptors within the group include SREB1 (GPR27), SREB2 (GPR85), and SREB3 (GPR173).National Center for Biotechnology Information, Conserved Protein Domain Family 7tmA_SREB1_GPR27, accessed 5 February 2022
