Kv4.3 is a potassium channel that is involved in the repolarisation of action potentials in cardiac muscle. Kv4.3 is not a classic cannabinoid receptor but its activity is modulated by cannabinoids.

Kv3.1 is a potassium channel that functions in action potential repolarisation in fast-firing neurons. Kv3.1 is not a classic cannabinoid receptor but its activity is modulated by cannabinoids.

GPR18 is involved in apoptosis, microglial migration in the CNS and other immune responses.

Cav3.2 is a calcium channel of the T-type that is involved in many processes in the brain and other tissues. Contrary to other calcium channels Cav3.2 is activated by relatively low/negative voltages.

Cav3.1 is a calcium channel of the T-type that is involved in many processes in the brain and other tissues. Contrary to other calcium channels Cav3.1 is activated by relatively low/negative voltages. Cav3.1 is not a classic cannabinoid receptor but its activity is modulated by cannabinoids. Since cannabinoids have a physiological effect on Cav3.1 it is effectively a cannabinoid receptor.

Cav3.3 is a calcium channel of the T-type that is involved in many brain processes. Contrary to other calcium channels Cav3.3 is activated by relatively low/negative voltages.
