Summary: Enables calcidiol 1-monooxygenase activity. Involved in calcitriol biosynthetic process from calciol; response to vitamin D; and vitamin D catabolic process. Acts upstream of or within calcium ion transport. Located in mitochondrion. Is expressed in several structures, including extraembryonic component; lower jaw molar; metanephros; and reproductive system. Used to study rickets. 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, Dec 2024]

Study in knockout mice provides evidence that bone 1alpha-hydroxylase Cyp27b1 may play a central role in the regulation of sclerostin, BMP2, and FGF23 in chronic kidney disease. Increased osteocytic 1,25(OH)2D production, triggered by renal malfunction, may represent a "primary defensive response" to protect the organism from ectopic calcification by increasing sclerostin and suppressing BMP2 production.

Deletion of both submodules eliminated basal Cyp27b1 expression and regulation in the kidney, leading to systemic and skeletal phenotypes similar to those of Cyp27b1-null mice

AQP-1 was decreased in renal papilla and AQP-4 expressions were increased in proximal tubule by suppressing renin activity or supplement of Vitamin D analogue. After injecting renin into the lateral ventricle of the 1alpha(OH)ase knockout mice, the renin expression level was decreased in the kidney, followed by the decrease of AQP-1 in renal papilla and increase of AQP-4 in proximal tubule

These results reveal that differential regulation of Cyp27b1 expression represents a mechanism whereby 1,25(OH)2D3 can fulfill separate functional roles, first in the kidney to control mineral homeostasis and second in extra-renal cells to regulate target genes linked to specific biological responses.

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.
