Receptor, calcidiol vitamin

Calcitriol acts like a steroid hormone, binding to, and activating, nuclear receptors that modulate gene expression. More than 50 genes are known to be regulated by calcitriol (see Table 3.3), but vitamin D response elements have only been identified in a relatively small number, including calcidiol 1-hydroxylase and 24-hydroxylase calbindin, a calcium binding protein in the...
