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. Since cannabinoids have a physiological effect on Kv3.1 it is effectively a cannabinoid receptor.

Distribution Summary

Kv3.1 channels are prominently expressed in brain (cerebellum > globus pallidus, subthalamic nucleus, substantia nigra > reticular thalamic nuclei, cortical and hippocampal interneurons > inferior colliculi, cochlear and vestibular nuclei), and in retinal ganglion cells.
