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.


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.
