Automated description from the Alliance of Genome Resources (Release 7.0.0)
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).
