Nav1.2 is a sodium channel that is involved in action potential generation in neurons and in muscle. Nav1.2 is not a classic cannabinoid receptor but its activity is modulated by cannabinoids.

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.

Kv1.5 is a potassium channel that is involved in restoring the resting membrane potential after depolarisation. Kv1.5 is not a classic cannabinoid receptor but its activity is modulated by cannabinoids.

Kv1.2 is a potassium channel that is responsible for maintaining resting membrane potential and regulating excitability in neurons. Kv1.2 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.

CB2 is primarily expressed in the immune cells and tissues of the body. Like CB1, CB2 is a G protein-coupled receptor which inhibits adenylyl cyclase and consequently lowers cAMP upon activation. This, in turn, regulates many second messenger pathways.

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.

Cav2.2 is a calcium channel of the N-type that is involved in many basal brain processes including learning and memory. Cav2.2 is not a classic cannabinoid receptor but its activity is modulated by cannabinoids. Since cannabinoids have a physiological effect on Cav2.2 it is effectively a cannabinoid receptor.

Cav2.1 is a calcium channel of the P/Q type that is central to many brain processes, including learning and memory. Cav2.1 is not a classic cannabinoid receptor but its activity is modulated by cannabinoids.
