Cnr1 Gene Summary [Rat]

Enables cannabinoid receptor activity. Involved in several processes, including modulation of chemical synaptic transmission; positive regulation of acute inflammatory response; and regulation of secretion by cell. Located in membrane raft and plasma membrane. Used to study several diseases, including Parkinsonism; cannabis abuse; diabetic neuropathy; impotence; and obesity. Biomarker of alcohol use disorder; obesity; and status epilepticus. Human ortholog(s) of this gene implicated in heroin dependence; obesity; schizophrenia; and type 2 diabetes mellitus. Orthologous to human CNR1 (cannabinoid receptor 1). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains

A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Cnr1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
