Background: Cannabinoid R2/CB2/CNR2

Cannabinoid R2 (Cannabinoid Receptor 2), also called CB2 or CNR2, is a 7TM protein that belongs to the family of G protein-coupled receptors, class A. Cannabinoid R2 is expressed in the periphery, notably by hematopoietic cells, in contrast to Cannabinoid R1 which is expressed predominantly in the central nervous system and gut. Cannabinoid R2 on lymphocytes and macrophages binds cannabinoids and modulates cytokine secretion. With the exception of their divergent C‑terminal tails, human Cannabinoid R2 shares 82% amino acid sequence identity with mouse and rat Cannabinoid R2.
