1-alpha-hydroxylase

25-Hydroxyvitamin D 1-alpha-hydroxylase (VD 1A hydroxylase) also known as calcidiol 1-monooxygenase[5] or cytochrome p450 27B1 (CYP27B1) or simply 1-alpha-hydroxylase is a cytochrome P450 enzyme that in humans is encoded by the CYP27B1 gene. [6][7][8]

25-hydroxyvitamin D3 1-alpha hydroxylase (CYP27B1) is an enzyme that catalyzes the conversion of 25-hydroxyvitamin D3 to its active form, 1,25-dihydroxyvitamin D3, playing a crucial role in regulating calcium homeostasis and epidermal differentiation.

This occurs in the renal proximal tubule via the regulation of the expression of two enzymes. 1-alpha-hyrdoxylase encoded by CYP27B1 results in the 1-hydroxylation of calcitriol and thus more active vitamin D.
