    text
  • is primarily located in the cytosol, however, lower levels of NQO1 have also been found in the nucleus, and also associated with mitotic spindles in cells undergoing division
    • basic FUNCTION
  • involved in detoxification pathways as well as in biosynthetic processes such as the vitamin k-dependent gamma-carboxylation of glutamate residues in prothrombin synthesis
  • may be involved in nitric oxide biosynthesis, response to toxin, synaptic transmission, cholinergic, xenobiotic metabolism
  • plays a role in suppressing inflammatory response and in attenuation of macrophage migration induced by LPS
  • belongs to the phase II detoxifying enzymes that are induced to protect against electrophilic insults, oxidative stress, and ionizing radiation
  • original role in the regulation of mRNA translation via the control of EIF4GI stability by the proteasome
  • rescue proteins containing intrinsically unstructured domains, such as TP53 and TP73, from degradation by the 20S proteasome
  • FAD containing quinone reductase that catalyzes the 2-electron reduction of a broad range of quinones
  • plays a key role in suppressing ionizing radiation (IR)-induced centrosome amplification and aneuploidy through a direct interaction with Aurora-A
  • xenobiotic metabolizing enzyme that detoxifies chemical stressors and antioxidants, providing cytoprotection in normal tissues
    • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS detoxification

  • to various forms of cancer
  • to breast cancer with poor survival
  • to artery plaques in type 2 diabetic patients
    • Variant & Polymorphism other
  • Cb09T TT phenotype with no NQO1 activity (susceptible)
  • allele 2 and 3 increases the risk of ALL
  • an increased risk of hematotoxicity after exposure to benzene
  • homozygote missense variant increasing the risk of breast cancer with poor survival
  • C609T polymorphism is associated with carotid artery plaques in type 2 diabetic patients (Han 2009)
