What is the Origin of CYP1B1?

The name CYP1B1 is a systematic nomenclature derived from its classification within the Cytochrome P450 enzyme superfamily, where 'CYP' indicates the superfamily, '1' is the gene family, 'B' is the subfamily, and '1' is the specific gene. The Cytochrome P450 enzymes were initially named for their characteristic absorption peak at 450 nm when bound to carbon monoxide. This systematic naming reflects its chemical function as a heme-containing monooxygenase responsible for hydroxylation reactions.

What is the Mechanism of CYP1B1?

The primary mechanism of CYP1B1 involves the hydroxylation of estrogen, specifically catalyzing the conversion of estradiol and estrone into 4-hydroxyestrone (4-OHE1) and 4-hydroxyestradiol (4-OHE2). This particular metabolic pathway is significant because the 4-hydroxy metabolites are considered highly reactive catechol estrogens that can potentially lead to DNA damage if not further detoxified. The enzyme's precise regulation is vital for maintaining a healthy estrogen metabolite ratio, thus playing a protective or risk-modulating role in hormone-sensitive tissues.

CYP1B1

Meaning

CYP1B1, or Cytochrome P450 1B1, is an enzyme belonging to the large superfamily of cytochrome P450 monooxygenases, primarily localized in the endoplasmic reticulum of cells. This enzyme is fundamentally involved in the metabolism of various endogenous compounds, notably including sex hormones like estrogen, as well as exogenous substances such as environmental toxins. Its activity is a critical determinant in the balance of estrogen metabolites, which influences cell proliferation and overall hormonal health.
