Anti-CYP27B1 antibodies are used in the immunodetection of the protein cytochrome P450 family 27 subfamily B member 1. In humans, the canonical protein has a reported length of 508 amino acid residues and a mass of 56.5 kDa. Its subcellular localization is in the mitochondria. A member of the Cytochrome P450 protein family, CYP27B1 is a cytochrome P450 monooxygenase involved in vitamin D metabolism and in calcium and phosphorus homeostasis. The CYP27B1 gene has been associated with the disease, Rickets vitamin D-dependent. Synonyms for this target antigen include CYP1, CYP1alpha, CYP27B, P450c1, PDDR, VDD1, VDDR, and CP2B. CYP27B1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. A number of CYP27B1 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
