  • Function

    May be involved in the sorting of secreted proteins (By similarity). May be involved in pre-B-cell growth. Antiretroviral defense protein, that blocks release of retrovirus from the cell surface. Depleted unpon HIV-1 infection by viral VPU protein through 20S proteasome degradation. Depleted upon infection by human Kaposi's sarcoma-associated herpesvirus (KSHV) through ubiquitination and subsequent degradation. May play a role in B-cell activation in rheumatoid arthritis.
  • Tissue specificity

    Predominantly expressed in liver, lung, heart and placenta. Lower levels in pancreas, kidney, skeletal muscle and brain. Overexpressed in multiple myeloma cells. Highly expressed during B-cell development, from pro-B precursors to plasma cells. Highly expressed on T-cells, monocytes, NK cells and dendritic cells (at protein level).
  • Sequence similarities

    Belongs to the tetherin family.
  • Domain

    The extracellular coiled coil domain is important for virus retention at the cell surface and prevention of virus spreading.
  • Post-translational

    Monoubiquitinated by KSHV E3 ubiquitin-protein ligase K5, leading to its targeting to late endosomes and degradation.
  • Cellular localization

    Golgi apparatus > trans-Golgi network. Cell membrane. Cell membrane. Late endosome. Targeted to late endosomes upon KSHV infection and subsequent ubiquitination. Targeted to the trans-Golgi network by viral VPU protein.

Thank you for your enquiry.

Unfortunately we are not aware of any publication using the ab88523. This does not mean that this antibody has not been used in a publication, it just means that we do not know about it.

I can however confirm that the laboratory has tested this antibody in immunohistochemistry on paraffin embedded sections and on human tissue. We do therefore guarantee this antibody in this application with our Abpromise guarantee (https://www.abcam.com/abpromise).

Should you need the antibody for staining in frozen section or on mouse tissue for example, please do contact me again with the details of your planned experiment, as I might be able to provide you with a testing discount.

I hope this information is helpful. Please do not hesitate to contact us again should you have any further questions.

I wish you a good evening!

According to our records, ab88523 was proving difficult to use in Western blot and we were in contact in order to help resolve the issue.
Looking at our correspondence, it appears that we are awaiting more details in order to help us better understand the difficulties experienced. If the requested information has already been sent, it appears that it did not reach our Scientific Support team and we apologize for this inconvenience. In this case we would like to ask for the information again so that we can reach a resolution.
If the issue has already been settled, please let us know so that we can be assured that the problem has been solved to your satisfaction and update our records.
We wish you the best of luck with your research and look forward to a reply.

Thank you for contacting us and letting us know about the trouble with this antibody.
I do have a couple of additional questions, so that I can better understand the situation:
1) Do you know your order number or lot number?
2) How has the antibody been stored?
3) What solution do you use for blocking the membrane (BSA or milk)?
4) How were the lysates prepared (reduced, denatured, protease inhibitors used)?
5) How much protein was loaded onto the gel per lane?
6) On the image that you sent, what are the top two molecular weight markers? I'm not sure if these are 40 and 50 kDa?
7) On the image, what is the difference between the lanes? Are these different lysates, and if so which is in each lane?
8) Were any of the cells treated in order to induce tetherin expression, or are you analyzing endogenous levels?
According to SwissProt, the tetherin primary amino acid sequence is cleaved to produce the mature protein, which removes 19 amino acids. This mature protein corresponds to about 18 kDa, which is close to the lower band on the image. However this mature protein is generally glycosylated and is seen by WB around 30 kDa using ab88523. At this point I'm not sure if the lower band on the image corresponds to tetherin.
We do guarantee all of our products to work as stated on the datasheet for up to 6 months after purchase, so I would be happy to send a replacement or alternatively issue a credit or refund. We also have ab14694, which as been cited in two references-
I look forward to hearing from you. Please let me know if you have any questions or if there is anything else that I can do for you.
