Target

  • Function

    Transcription factor that recognizes and binds to the enhancer heptamer motif 5'-TGA[CG]TCA-3'. Promotes activity of NR5A1 when phosphorylated by HIPK3 leading to increased steroidogenic gene expression upon cAMP signaling pathway stimulation. Involved in activated KRAS-mediated transcriptional activation of USP28 in colorectal cancer (CRC) cells (PubMed:24623306). Binds to the USP28 promoter in colorectal cancer (CRC) cells (PubMed:24623306).

  • Sequence similarities

    Belongs to the bZIP family. Jun subfamily.
    Contains 1 bZIP (basic-leucine zipper) domain.

  • Post-translational
    modifications

    Ubiquitinated by the SCF(FBXW7), leading to its degradation. Ubiquitination takes place following phosphorylation, that promotes interaction with FBXW7.
    Phosphorylated by CaMK4 and PRKDC; phosphorylation enhances the transcriptional activity. Phosphorylated by HIPK3. Phosphorylated by DYRK2 at Ser-243; this primes the protein for subsequent phosphorylation by GSK3B at Thr-239. Phosphorylated at Thr-239, Ser-243 and Ser-249 by GSK3B; phosphorylation reduces its ability to bind DNA. Phosphorylated by PAK2 at Thr-2, Thr-8, Thr-89, Thr-93 and Thr-286 thereby promoting JUN-mediated cell proliferation and transformation. Phosphorylated by PLK3 following hypoxia or UV irradiation, leading to increase DNA-binding activity.
    Acetylated at Lys-271 by EP300.

Answer

Thank you for your enquiry regarding ab31419 and ab47476; and for taking the time to provide some useful details of the experiments. I am very sorry to hear that your customer is having problems with these two antibodies.
I would like to reassure you that our Abpromise applies to your complaint since you purchased this product within the guarantee period. This means that in the event that a product is not functioning in the applications/species cited on the product data sheet (and the problem has been reported within 6 months of purchase) we will happily offer a credit note/refund to the value of the product purchased.
After reading through the detailed protocol you kindly forwarded to Abcam, I would like to make the following comments/suggestions:
1) The loaded amount of protein seems to be a bit low: 5 μg/lane, normally we would suggest loading at least 25-30 μg/lane protein per lane.
2) Since c-Jun and ATF2 are both mainly present in the nuclei, it would be worth preparing nuclear fraction (rather than whole cell lysate) to enrich the target proteins in the sample if it is possible and apply them for WB.
3) Customer may also need to test different dilutions (1/500 or even 1/250) to make sure that the experiment is carried out under the optimal conditions. This is even more important since only 5 μg instead of 30 μg lysate was loaded.
I hope this will be useful for you. Should you still have any problem with this antibody after following these suggestions, then please do not hesitate to contact our Technical Department again.

Answer

Thank you very much for contacting us.

I just wanted to let you know that I am still working on your inquiry. I have contacted the originator of this product for the information you requested, and I am awaiting a reply.

I can provide some information regarding postive controls for this product. This antibody has been tested successfully in the following tissues/cell lines as shown in on the datasheet and within publicatiobns referenced:

Hela, Jurkat, Mouse small bowel adenoma, U2OS, 3T3, COS7, PC12 , Primary Prostate Epithelia [PMID: 19592505], dorsal mouse skin [PMID: 19762425]


I am very sorry for the delay. I will forward to you the information as soon as I receive it. Thank you for your patience.

Question

Thanks for your fast answer, I would maybe preffer to try a different
antibody. For my experiments, I also need an antibody afainst c-Fos for
ChIP, dou you have one? The oligo was ordered on 12th october 2011 and we
got it one day later. for the ChIP I´ve tried using 2.5 and 5ug of antibody
and in the WB I´ve used dilution 1/500.

Answer

Thank you for your reply.

Unfortunately we do not have another C-Jun antibody that is tested in ChIP. Please let me know how you would like to proceed. We do not currently stock a C-Fos antibody that will work in ChIP but if you would like to test an antibody then please let me know. You may be eligible for a testing discount.

I look forward to your reply.

Answer

Thank you for your reply and with clarifying information.

We have not received any other complaints about this antibody, so I am sorry to hear you have been experiencing problems. It is troubling that it is not working in both ChIP and WB. I would like to offer you a replacement vial of the same or an alternative product, or a refund/credit. Please could you confirm your preference and also provide the following details:

- Date of order/delivery
- Primary antibody dilution

I look forward to your reply.
