Background: Cannabinoid Receptor 1, CNR1 also known as CB1, is involved in cannabinoid induced CNS effects. It acts by inhibiting intracellular adenylate cyclase activity and could be a receptor for anandamide. CNR1 is a potential target for the development of novel therapeutic drugs in the treatment of various conditions, such as pain, feeding disorders, vascular disease, Parkinson’s disease, and other central nerve system disorders. CB1A is a truncated isoform of CB1 mutant which is resulted from the removal of 89 amino acid in N-terminus and substituted with 28 amino acids by frame shift. This mutant is distributed throughout the brain and peripheral tissue together with CB1.
