[edit] The missing subtype?

I've found a bunch of sources that say there are six subtypes (L, N, P, Q, R, and T), and one source ^* that says there are seven, but does not list them! Does anyone know what this missing subtype is? Thanks much, delldot | talk 18:34, 22 April 2006 (UTC)

^* Kim AH, Kerchner GA, and Choi DW. 2002. Blocking Excitotoxicity. Chapter 1 in: CNS Neuroproteciton. Marcoux FW and Choi DW, editors. Springer, New York. pp. 3 - 36.

There are only five actually: L, T, N, P/Q, and R. Of course, there are 4 L-type channels and three T-type channels for a total of 10 channels total. At least, this is how many α-1 subunits there are. See Hille's book, any review, or: http://www.neuro.wustl.edu/neuromuscular/mother/chan.html#ca for examples. -Dpryan 06:31, 2 August 2006 (UTC)

Is the P/Q chanel just one channel or two?!?

One gene->two channels. Q is an alternatively spliced form of P...so kind of one channel and kind of two, depending on how you define things. --Dpryan 19:23, 16 September 2006 (UTC)

Hasn't the nomenclature for voltage gated ion channels changed? Last thing I read L channels were now called Cav1.1-1.4, P channels are Cav 2.1, and N channels are Cav2.2, and so forth...
