The transport of calcium across the enterocyte cytoplasm appears to be rate-limiting for calcium absorption in the intestine; the presence of calbindin increases the amount of calcium crossing the cell without raising the free concentration. Calbindin-D9k may also stimulate the basolateral calcium-pumping ATPases. Expression of calbindin-D9k and calbindin-D28k are both stimulated by the active vitamin D metabolite, calcitriol although the precise mechanisms are still controversial. In mice in which the receptor for vitamin D is not expressed, calbindin-D9k is reduced, but not absent.
