Summaries for CNR1 Gene

Entrez Gene Summary for CNR1 Gene

  • This gene encodes one of two cannabinoid receptors. The cannabinoids, principally delta-9-tetrahydrocannabinol and synthetic analogs, are psychoactive ingredients of marijuana. The cannabinoid receptors are members of the guanine-nucleotide-binding protein (G-protein) coupled receptor family, which inhibit adenylate cyclase activity in a dose-dependent, stereoselective and pertussis toxin-sensitive manner. The two receptors have been found to be involved in the cannabinoid-induced CNS effects (including alterations in mood and cognition) experienced by users of marijuana. Multiple transcript variants encoding two different protein isoforms have been described for this gene. [provided by RefSeq, May 2009]

GeneCards Summary for CNR1 Gene

CNR1 (Cannabinoid Receptor 1) is a Protein Coding gene. Diseases associated with CNR1 include Cannabis Dependence and Cannabis Abuse. Among its related pathways are Peptide ligand-binding receptors and Ibuprofen Pathway, Pharmacodynamics. GO annotations related to this gene include G-protein coupled receptor activity and cannabinoid receptor activity. An important paralog of this gene is CNR2.

UniProtKB/Swiss-Prot for CNR1 Gene

  • Involved in cannabinoid-induced CNS effects. Acts by inhibiting adenylate cyclase. Could be a receptor for anandamide. Inhibits L-type Ca(2+) channel current. Isoform 2 and isoform 3 have altered ligand binding.

Tocris Summary for CNR1 Gene

  • The CB1 receptor, also known as the central cannabinoid receptor, is a member of the cannabinoid receptor group of G-protein-coupled receptors that also includes CB2 and GPR55. CB1 receptors are found mainly in the terminals of central and peripheral neurons.
