Comment typeDescription
Catalytic ActivityCalcidiol + NADPH + O(2) = calcitriol + NADP(+) + H(2)O.
CofactorName=heme; Xref=ChEBI:CHEBI:30413; Evidence={ECO:0000250};
DiseaseRickets vitamin D-dependent 1A (VDDR1A) [MIM:264700]: A disorder caused by a selective deficiency of the active form of vitamin D (1,25-dihydroxyvitamin D3) and resulting in defective bone mineralization and clinical features of rickets. {ECO:0000269|PubMed:10320521, ECO:0000269|PubMed:10566658, ECO:0000269|PubMed:12050193, ECO:0000269|PubMed:9486994, ECO:0000269|PubMed:9837822}. Note=The disease is caused by mutations affecting the gene represented in this entry.
FunctionCatalyzes the conversion of 25-hydroxyvitamin D3 (25(OH)D) to 1-alpha,25-dihydroxyvitamin D3 (1,25(OH)2D) plays an important role in normal bone growth, calcium metabolism, and tissue differentiation.
PathwayHormone biosynthesis; cholecalciferol biosynthesis.
SimilarityBelongs to the cytochrome P450 family. {ECO:0000305}.
Subcellular LocationMitochondrion membrane.
Tissue SpecificityKidney.
