P450 Oxidoreductase

First report of a novel protein destabilization mutation in human P450 oxidoreductase.


The L374H mutation in POR causes POR deficiency and disordered steroid metabolism.

Off-target effect of Abiraterone, an anti-prostate cancer drug

Anti-prostate cancer drug abiraterone which inhibits CYP17A1 activities was found to strongly inhibit 21-hydroxylase activity of CYP21A2.

Altered aromatase and CYP3A4 activities due to mutations in POR

We found some common POR polymorphisms thought to be normal can cause loss of function with aromatase and CYP3A4
