CNR2
GeneName
CNR2
Summary
CNR2, also known as CB2 or cannabinoid receptor 2, is a 40kDa G protein-coupled receptor primarily expressed in the immune system and the central nervous system, particularly in the brain regions associated with pain and inflammation. It is localised in various cellular components, including the plasma membrane, dendrites, and the endoplasmic reticulum. CNR2 plays a vital role in mediating the effects of cannabinoids, influencing processes such as immune response, inflammatory response, and synaptic transmission. Its activation is involved in the regulation of leukocyte chemotaxis and the modulation of synaptic signalling through endocannabinoids.
Importance
CNR2 is relevant to: - The modulation of immune responses, making it a target for therapies in autoimmune diseases and inflammation. - Pain management, as it is implicated in pain signalling pathways and may offer alternatives to traditional analgesics. - Neurological research, particularly in conditions like multiple sclerosis, where cannabinoid signalling may influence disease progression. - The study of addiction and substance use disorders, given its role in the response to amphetamines and other substances.
Top Products

Function
Heterotrimeric G protein-coupled receptor for endocannabinoid 2-arachidonoylglycerol mediating inhibition of adenylate cyclase. May function in inflammatory response, nociceptive transmission and bone homeostasis.
Post-translational modifications
Constitutively phosphorylated on Ser-352; phosphorylation increases cell internalization and desensitizes the receptor.
Sequence Similarities
Belongs to the G-protein coupled receptor 1 family.
Tissue Specificity
Preferentially expressed in cells of the immune system with higher expression in B-cells and NK cells (at protein level). Expressed in skin in suprabasal layers and hair follicles (at protein level). Highly expressed in tonsil and to a lower extent in spleen, peripheral blood mononuclear cells, and thymus. PubMed:14657172 could not detect expression in normal brain. Expressed in brain by perivascular microglial cells and dorsal root ganglion sensory neurons (at protein level). Two isoforms are produced by alternative promoter usage and differ only in the 5' UTR: isoform CB2A is observed predominantly in testis with some expression in brain, while isoform CB2B is predominant in spleen and leukocytes.
Cellular localization
