text: Seasonal changes in the number of pore-forming alpha subunits of the L-type Ca2+ channels (DHPRs, dihydropyridine receptors) in crucian carp heart have been measured by [methyl-3H]PN200-110 binding (Vornanen and Paajanen, 2004) and show that the number of Ca2+ channels are approximately doubled for a relatively short period of time in mid-summer (May–July), i.e., for the major part of the year the density of Ca2+ channels is low (Figure 9.14).
