Scientific background

T-type Ca2+ channels play an important role in many cellular processes such as hormone secretion, neurotransmitter release and cell differentiation.  

T-type channels are also known to participate in the pacemaker activities of the heart and neurons including thalamic neurons.1 Three genes encoding T-type Ca2+ channels have been cloned and designated as CaV3.1 (CACNA1G), CaV3.2 (CACNA1H) and CaV3.3 (CACNA1I).1-3  

While CaV3.1 and CaV3.2 are widely expressed in various tissues, CaV3.3 is primarily expressed in the central nervous system, where high expression has been described in thalamic neurons.  

The Ca2+ current generated by the CaV3.3 channel displays much slower activation and inactivation compared to the currents produced by CaV3.1 and CaV3.2, suggesting it might play a different role in neuronal excitability.1,4
