Summaries for CYP27B1 Gene

Entrez Gene Summary for CYP27B1 Gene

  • This gene encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. The protein encoded by this gene localizes to the inner mitochondrial membrane where it hydroxylates 25-hydroxyvitamin D3 at the 1alpha position. This reaction synthesizes 1alpha,25-dihydroxyvitamin D3, the active form of vitamin D3, which binds to the vitamin D receptor and regulates calcium metabolism. Thus this enzyme regulates the level of biologically active vitamin D and plays an important role in calcium homeostasis. Mutations in this gene can result in vitamin D-dependent rickets type I.

GeneCards Summary for CYP27B1 Gene

CYP27B1 (Cytochrome P450 Family 27 Subfamily B Member 1) is a Protein Coding gene. Diseases associated with CYP27B1 include vitamin d-dependent rickets, type i and hypocalcemic vitamin d-dependent rickets. Among its related pathways are Gene Expression and Metabolism. GO annotations related to this gene include iron ion binding and oxidoreductase activity, acting on paired donors, with incorporation or reduction of molecular oxygen. An important paralog of this gene is CYP11B1.
