Supplementary information

NQO2 also known as NRH:quinone oxidoreductase 2 is a flavoprotein enzyme playing roles in cellular redox reactions. It has a molecular mass of approximately 25 kDa. NQO2 is expressed widely in human tissues such as liver colon and brain. It catalyzes the two-electron reduction of quinones to hydroquinones therefore helping prevent oxidative stress by converting reactive quinone species into less reactive and more stable molecules. The protein often interacts with other cellular components to perform its functions effectively.
Biological function summary

NQO2 participates in detoxification processes and acts as a dihydronicotinamide riboside:quinone oxidoreductase. Although it is not part of a large protein complex NQO2 may associate with other molecules or enzymes that modulate cellular antioxidant defense systems. It serves as a backup system when other primary antioxidant enzymes such as NQO1 are impaired. This function reflects the importance of NQO2 in maintaining cellular health and response to environmental stresses.

Pathways

NQO2 is involved in metabolism and oxidative stress response pathways. Its role in quinone detoxification connects it to the cellular defense mechanism against oxidative damage interacting with proteins like NQO1. NQO2's enzymatic activity goes hand-in-hand with the NAD(P)H dehydrogenase (quinone) pathway which collaborates with other proteins to maintain redox homeostasis and protect cells against electrophilic and oxidative stress.

Alterations in NQO2 expression or function are linked to cancer and neurodegenerative diseases. NQO2's involvement in detoxifying potent quinones links it to cancerous developments when these processes fail while its role against oxidative stress connects it to neurodegenerative conditions like Parkinson’s disease. During these conditions interactions with proteins such as NQO1 and p53 can be significant. The balance of NQO2 activity may contribute to disease progression or suppression highlighting its therapeutic potential in disease management.

Target data

The enzyme apparently serves as a quinone reductase in connection with conjugation reactions of hydroquinones involved in detoxification pathways as well as in biosynthetic processes such as the vitamin K-dependent gamma-carboxylation of glutamate residues in prothrombin synthesis.
