CYP4B1 is a member of the cytochrome P450 (CYP450) superfamily of heme-thiolate proteins that catalyze mono-oxygenase reactions and partake in the metabolism of a wide range of endogenous and xenobiotic compounds, such as lipids, steroids and drugs. The CYP4 proteins are primarily involved in fatty acid metabolism, and possess ω-hydroxylation activity. CYP4B1 is distinguished from other family members by its increased capacity to catalyze ω-hydroxylation of smaller fatty-acids and n-alkanes. It is predominantly expressed in the lung, with low levels in the heart, skeletal muscle and kidney. A long non-coding RNA (lncRNA) of CYP4B1 has been associated with diabetic nephropathy pathogenesis. A polymorphism in this gene associated with glomerular filtration rate in pediatric patients with sickle cell disease.

Synonyms: CYPIVB1 , P-450HP
