The protein encoded by this gene is an adenosine receptor that belongs to the G-protein coupled receptor 1 family. There are 3 types of adenosine receptors, each with a specific pattern of ligand binding and tissue distribution, and together they regulate a diverse set of physiologic functions. The type A1 receptors inhibit adenylyl cyclase, and play a role in the fertilization process. Animal studies also suggest a role for A1 receptors in kidney function and ethanol intoxication. Transcript variants with alternative splicing in the 5' UTR have been found for this gene. [provided by RefSeq, Jul 2008]
Forensic Context
A study in domestic swine demonstrated that the ADORA1 exhibited higher expression in the border zone of the heart compared to the ischemic region one day after induced myocardial infarction, with its repression in the ischemic zone confirmed at the protein level by Western blot [Kaikkonen et al.
