What is the official name of the CYP1B1 gene?
The official name of this gene is “cytochrome P450 family 1 subfamily B member 1.”
CYP1B1 is the gene's official symbol. The CYP1B1 gene is also known by other names, listed below.

What is the normal function of the CYP1B1 gene?
The CYP1B1 gene provides instructions for producing an enzyme that is a member of the cytochrome P450 family of enzymes. These enzymes are involved in many processes in the body, such as assisting with reactions that break down drugs and produce certain fats (lipids). The CYP1B1 enzyme participates in biochemical reactions in which an oxygen atom is added to other molecules.
The CYP1B1 enzyme is active in many tissues, including structures of the eye. The function of the CYP1B1 enzyme in the development of the eye is unclear, but it may play a role in forming structures at the front of the eye and may also be involved in a process that regulates the secretion of fluid inside the eye.
Does the CYP1B1 gene share characteristics with other genes?
The CYP1B1 gene belongs to a family of genes called CYP (cytochrome P450s).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
