ADORA1 Membrane Protein
The adenosine A1 receptor (ADORA1) belongs to the adenosine receptor group of G protein-coupled receptors which use adenosine as endogenous ligand. The A1 receptor includes A2A, A2B, and A3 and displays high expression levels in the brain (cortex, cerebellum, hippocampus), dorsal horn of the spinal cord, eye and atria. ADORA1 is encoded by the ADORA1 gene. An important paralog of this gene is ADORA2A.
