CB1 / TRP channels
Name: Cannabinoid receptor 1
(CB1)
Official Symbol: CNR1
provided by HGNC
Function:
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.
