Summary: Enables calcidiol 1-monooxygenase activity. Involved in several processes, including negative regulation of bone trabecula formation; positive regulation of parathyroid hormone secretion; and vitamin D catabolic process. Predicted to be located in cytoplasm. Predicted to be active in mitochondrion. Used to study Wilson disease; acute kidney failure; nephrosis; and vitamin D-dependent rickets type 1A. Human ortholog(s) of this gene implicated in hepatitis B; obesity; rickets; type 1 diabetes mellitus; and vitamin D-dependent rickets type 1A. Orthologous to human CYP27B1 (cytochrome P450 family 27 subfamily B member 1). [provided by Alliance of Genome Resources, Nov 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
