Protein
1,25-dihydroxyvitamin D(3) 24-hydroxylase, mitochondrial
Gene
Cyp24a1, Cyp24
Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Has a role in maintaining calcium homeostasis. Catalyzes the NADPH-dependent 24-hydroxylation of calcidiol (25-hydroxyvitamin D3) and calcitriol (1-alpha,25-dihydroxyvitamin D3). The enzyme can perform up to 6 rounds of hydroxylation of calcitriol leading to calcitroic acid.

Catalytic activityi

Calcitriol + NADPH + O2 = calcitetrol + NADP+ + H2O.1 Publication
Calcidiol + NADPH + O2 = secalciferol + NADP+ + H2O.1 Publication

Cofactori

Heme group.1 Publication

Kineticsi

  1. KM=2.8 µM for calcidiol1 Publication

pH dependencei

Optimum pH is 7.7.
