Overlay histogram showing A549 cells stained with ab196465 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab196465, 1/500 dilution) for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) Alexa Fluor® 488 used at the same concentration and conditions as the primary antibody. Unlabelled sample (blue line) was also used as a control.

Acquisition of >5,000 events were collected using a 20mW Argon ion laser (488nm) and 525/30 bandpass filter.

This antibody gave a positive signal in A549 fixed with 4% formaldehyde (10 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.

Supplementary information

NQO1 also known as NAD(P)H:quinone oxidoreductase 1 is a cytosolic enzyme involved in two-electron reduction processes. This protein plays a role in detoxification transforming quinones into less reactive and harmful hydroquinones. NQO1 has a molecular weight of approximately 31 kDa and is present in various tissues with high expression in the liver and lungs. Sometimes called DT-diaphorase it contributes to antioxidant protection within cells and assists in the stabilization of other proteins such as p53.
Biological function summary

NQO1 serves a protective function against oxidative stress by reducing quinones and preventing redox cycling that generates reactive oxygen species. Part of a critical network its function integrates with the cellular defense mechanism assisting in maintaining cellular homeostasis. NQO1 helps metabolize xenobiotics and is associated with phase II detoxification working alongside enzymes like glutathione S-transferases but is not part of a complex.

Pathways

NQO1 is an important component of the antioxidant defense pathway participating in the direct enzymatic reduction of quinones protecting cells from oxidative damage. It also interfaces with the KEAP1-NRF2 pathway where the NQO1 gene is regulated by the NRF2 transcription factor that upregulates its expression in response to oxidative stress. NQO1 interlinks with proteins such as p53 through pathways related to apoptotic regulation and cellular stress responses.

Mutations or altered expression of NQO1 have correlations with cancer development and progression notably in liver and lung cancers. This protein's stability influences cancer cell survival particularly under oxidative stress or chemotherapeutic treatments. NQO1 also exhibits links to Alzheimer's disease where its potential role in neuroprotection against oxidative damage draws investigation relating it to proteins like tau and amyloid-beta.

Target data

Flavin-containing quinone reductase that catalyzes two-electron reduction of quinones to hydroquinones using either NADH or NADPH as electron donors. In a ping-pong kinetic mechanism, the electrons are sequentially transferred from NAD(P)H to flavin cofactor and then from reduced flavin to the quinone, bypassing the formation of semiquinone and reactive oxygen species (By similarity) (PubMed : 8999809, PubMed : 9271353). Regulates cellular redox state primarily through quinone detoxification. Reduces components of plasma membrane redox system such as coenzyme Q and vitamin quinones, producing antioxidant hydroquinone forms. In the process may function as superoxide scavenger to prevent hydroquinone oxidation and facilitate excretion (PubMed : 15102952, PubMed : 8999809, PubMed : 9271353). Alternatively, can activate quinones and their derivatives by generating redox reactive hydroquinones with DNA cross-linking antitumor potential (PubMed : 8999809). Acts as a gatekeeper of the core 20S proteasome known to degrade proteins with unstructured regions. Upon oxidative stress, interacts with tumor suppressors TP53 and TP73 in a NADH-dependent way and inhibits their ubiquitin-independent degradation by the 20S proteasome (PubMed : 15687255, PubMed : 28291250).
