Function

Constitutive NADPH oxidase which generates superoxide intracellularly upon formation of a complex with CYBA/p22phox. Regulates signaling cascades probably through phosphatases inhibition. May function as an oxygen sensor regulating the KCNK3/TASK-1 potassium channel and HIF1A activity. May regulate insulin signaling cascade. May play a role in apoptosis, bone resorption and lipolysaccharide-mediated activation of NFKB. May produce superoxide in the nucleus and play a role in regulating gene expression upon cell stimulation. Isoform 3 is not functional. Isoform 4 displays an increased activity. Isoform 5 and isoform 6 display reduced activity.
Tissue specificity

Expressed by distal tubular cells in kidney cortex and in endothelial cells (at protein level). Widely expressed. Strongly expressed in kidney and to a lower extent in heart, adipocytes, hepatoma, endothelial cells, skeletal muscle, brain, several brain tumor cell lines and airway epithelial cells.
Sequence similarities

Contains 1 FAD-binding FR-type domain.
Contains 1 ferric oxidoreductase domain.
Developmental stage

Expressed in fetal kidney and fetal liver.
Post-translational
modifications

Isoform 3 and isoform 4 are N-glycosylated. Isoform 4 glycosylation is required for its proper function.
Cellular localization

Endoplasmic reticulum membrane. Cell membrane. Cell junction > focal adhesion. Nucleus. May localize to plasma membrane and focal adhesions. According to PubMed:15927447, may also localize to the nucleus.

Question

If only the monoclonal antibodies behaved as this paper suggests. After looking at the paper, the supplimental data and figure 1 clearly demonstrates that with HEK293 cells alone there should only be a faint band observed (which is my vector control) and the over expression of NOX4 gives a clear, dark band. In my hands with the same system (where I can show the NOX4 is overexpressed both by increased p22 due to stabilization through NOX4 interaction and by Myc tag - as well as higher H2O2 production against the vector control which I haven't shown you) I am not seeing this result - the vector control should show a faint band relative to the overexpressed NOX4 HEK293 cells. I can't verify what the authors of this paper have done/published, I only know that my data does not support these results. I would still greatly appreciate a refund for these antibodies (order#1152887), and urge caution with these antibodies as I am still concerned they are not truly recognizing NOX4.

Question

To whom it may concern,
I am emailing in regards to order #***placed with Abcam on ****, requesting 4 antibodies (ab109225, ab133303, ab60940 and ab61248) against the protein NOX4. Our research is in the NOX/DUOX protein family and their implication in cancer, and we have been searching for an antibody that recognizes the NOX4protein. Attached is the results of our western blots of an overexpression system for NOX4 (vector control vs 5' Myc tagged NOX4 overexpressed in HEK293) as well as a NOX4 clone (clone F), and SKMEL5 cells which have an albeit low RNA level of NOX4. The results of your antibodies (while the Myc tag control loaded at the same time, same day for all gels/westerns clearly shows overexpressed NOX4) do not demonstrate these antibodies are detecting NOX4 at all, as the 5' overexpression should clearly demonstrate a higher level of NOX4 than the vector control. I believe the antibody is recognizing an HEK protein, simply not NOX4 (plus the RNA levels of NOX4 in HEK are around 800-2000, even lower than SKMEL5, so really no band should be visible for the vector control lane). It is an acknowledged problem in the field that companies cannot create a good antibody to recognize this protein (see Babelova, A. et al Free Radic Biol Med. 2012, 15, 842-853, Figure 1D), we simply had hopes these antibodies might work. As we are unsatisfied with the results, I am requesting that the monies used for purchase be refunded to our account at the NIH.

Asked on Oct 11 2012

Answer

Thank you for contacting Abcam.

After having talked with the lab, we agree that your data looks good. I see that there is a band near 63 KDa (the expected molecular weight) with all of the antibodies and even in couple of your blots there looks to small increases in expression levels in your transfected lanes.

Unfortunately, we do not have QC data that we can send to show specificity, however, two of these antibodies (ab109225 (3187-1) & ab133303 (#3174-1) ) were produced as part of a collaboration and they ran controls to verify that the antibody is specific to NOX4. I would refer you to the Results section of the following publication because they state that the antibody has been confirmed to be specific ("Using lysates from both Nox4 overexpressing cells and cells from Nox4 knockout mice, we confirmed the specificity of both the rabbit polyclonal (not shown) and monoclonal Nox4 antibodies"):

Lee, C.F., Qiao, M. Schroeder, K., Zhao, Q. and Asmis, R., Nox4 is a novel inducible source of reactive oxygen species in monocytes and macrophages and mediates oxidized low density lipoprotein-induced macrophage death. ,Circ.Res. 106(9): 1489-97 (2010).

If after looking at this paper, you still do not agree with the results, then please let me know and I will process a refund.

Please let me know if you have any further questions.

Answer

Thank you for contacting us.

This product was developed by one of our collaborator university laboratory. They are having difficulties in product so the product is unpublished momentarily.

The product ab109225 is a rabbit monoclonal antibody against NOX4 and is a different product. I would suggest trying this product as alternative.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Asked on Jun 11 2012

Answer

Thank you for contacting us.
I am sorry to hear that the antibody is not working as stated on the datasheet.

As we discussed over the phone, I would suggest the following:
1) load more protein (e.g. 30- 50 ug) use more antibody
2) use more primary antibody (e.g. 1/500)

Please let me know if these tips are of help or not.
If not, I'd be happy to discuss other options to resolve this problem if the antibody was purchased within the last 6 months.

I wish you good luck and look forward to hear back from you.
