    靶标

    • 功能

      E3 ubiquitin-protein ligase that mediates ubiquitination of p53/TP53, leading to its degradation by the proteasome. Inhibits p53/TP53- and p73/TP73-mediated cell cycle arrest and apoptosis by binding its transcriptional activation domain. Also acts as an ubiquitin ligase E3 toward itself and ARRB1. Permits the nuclear export of p53/TP53. Promotes proteasome-dependent ubiquitin-independent degradation of retinoblastoma RB1 protein. Inhibits DAXX-mediated apoptosis by inducing its ubiquitination and degradation. Component of the TRIM28/KAP1-MDM2-p53/TP53 complex involved in stabilizing p53/TP53. Also component of the TRIM28/KAP1-ERBB4-MDM2 complex which links growth factor and DNA damage response pathways.

    • 组织特异性

      Ubiquitous. Isoform Mdm2-A, isoform Mdm2-B, isoform Mdm2-C, isoform Mdm2-D, isoform Mdm2-E, isoform Mdm2-F and isoform Mdm2-G are observed in a range of cancers but absent in normal tissues.

    • 疾病相关

      Note=Seems to be amplified in certain tumors (including soft tissue sarcomas, osteosarcomas and gliomas). A higher frequency of splice variants lacking p53 binding domain sequences was found in late-stage and high-grade ovarian and bladder carcinomas. Four of the splice variants show loss of p53 binding.

    • 序列相似性

      Belongs to the MDM2/MDM4 family.
      Contains 1 RanBP2-type zinc finger.
      Contains 1 RING-type zinc finger.
      Contains 1 SWIB domain.

    • 结构域

      Region I is sufficient for binding p53 and inhibiting its G1 arrest and apoptosis functions. It also binds p73 and E2F1. Region II contains most of a central acidic region required for interaction with ribosomal protein L5 and a putative C4-type zinc finger. The RING finger domain which coordinates two molecules of zinc interacts specifically with RNA whether or not zinc is present and mediates the heterooligomerization with MDM4. It is also essential for its ubiquitin ligase E3 activity toward p53 and itself.

    • 翻译后修饰

      Phosphorylated in response to ionizing radiation in an ATM-dependent manner.
      Auto-ubiquitinated; which leads to proteasomal degradation. Deubiquitinated by USP2 leads to its accumulation and increases deubiquitinilation and degradation of p53/TP53. Deubiquitinated by USP7; leading to stabilize it.

    • 细胞定位

      Nucleus > nucleoplasm. Cytoplasm. Nucleus > nucleolus. Expressed predominantly in the nucleoplasm. Interaction with ARF(P14) results in the localization of both proteins to the nucleolus. The nucleolar localization signals in both ARF(P14) and MDM2 may be necessary to allow efficient nucleolar localization of both proteins. Colocalizes with RASSF1 isoform A in the nucleus.

      Question

      Thanks for the help. Regarding the isoforms, I checked the literatures, please see this: http://mcb.asm.org/content/early/2006/10/23/MCB.00235-06.short

      Proteins encoded by the mdm2 gene, which has a pivotal role in the regulation of

      22 growth and differentiation, exist principally in human and murine cells as two

      23 isoforms that migrate in gels as 75 kDa and 90 kDa proteins

      So I think both green bands between 50 and 100 are MDM2s.

      Please help me confirm it.

      Read More
      Answer

      Thank you for your reply.

      Based on the information that you were able to supply, I would agree with you that these bands are MDM2.

      If there is anything else I can help you with, please just let me know.

      Question

      Thanks for providing me the new antibody. I am quite amazed with how fast you guys could replace it and deliver it within one day.

      I performed new Western with the new AB yesterday and today. Here, I am sending you the image.

      I basically get three potential bands (green). Would you please help me determine which green band is actually MDM2? Because they are all not 55kD.

      Read More
      Answer

      Thank you for your reply.

      I have attached your western blot with an arrow pointing to what I think is the correct band. I picked that band as looking at the western blot data that is on the webpage for this antibody, it appears to be recognizing a band at a higher molecular weight than 55kDa.

      I am not familiar with this protein, but could there be multiple isoforms of the protein and this antibody is detecting one that is slightly higher.

      Please let me know if there is anything else I can help you with.

      Question

      Thanks for your prompt reply. My samples are from human melanoma cell lines.

      For your questions, I loaded 150 ug per lane and the antibody dilution is 1:200.

      Here, I am sending you the images of my WB of MDM2 and p53 for the same samples. The red bands are Actin as controls. The green bands are supposed to be either P53 or MDM2 respectively.

      I would like to try another antibody from your company as I always like to use your antibodies.

      Answer

      Thank you for your reply.

      I am actually based on out of the Eugene, Or office, or else it would be great to talk to you in person. If you would like to drop in and talk to one of my colleagues based in the Kendall Sq office, I am sure they would be happy to meet you.

      I agree with your assessment of theMDM2 antibody and therefore I would be very happy to offer you a replacement antibody of your choice. Some of our other MDM2 antibodies that should work in human cells in western blot are:

      https://www.abcam.com/MDM2-antibody-ab58530.html



      Please let me know which one you would like to receive and I will arrange for it to be sent to you, or have it available for you to pick up.

      I hope your day is going well.

      Question

      I ordered this antibody in March (Anti-MDM2 antibody [SMP 14] ab3110). It turned out no alleged band of MDM2 detected.

      I am pretty good at antibody optimization, no don’t let me add more protein or use more antibody (I’ve already tried).

      I just want to know, you have 4 antibodies against MDM2, which one is the best for WB detection of it?

      If you could give me some clue, it will be greatly appreciated.

      Read More
      Answer

      Thank you for contacting Abcam.

      I am sorry about the issues you are having with ab3110 in western blot. The antibody is covered under our Abpromise for six months and is guaranteed to work in western blot onmouse, rat and humansamples . If we cannot resolve the issue you are having with the antibody then I would be happy to either send a replacement antibody or to process a refund.

      I know that you tried various protein and antibody concentrations, but I was wondering if you could provide that information, along with the species of the sample that you are loading. Just so we have that information for our records.

      Also, as we have a number of antibodies against MDM2, once I know which species of sample you are using, I will be able to help select the appropriate antibody for you.

      I look froward to your reply.

      Question

      One of my costumers wants to use anti-MDM2, SMP14 (code. ab3110) in WB assays with rat specimen.

      Data Sheet says that clone SMP14 cross reacts with rat, but reading the answers for other costumers' technical doubts at ABCAM site, now I have questions:


      1-) If there is no information about the human MDM2 sequence detected by ab3110 in rat, how is it possible to affirm that it crossreacts with samples of this animal?



      2-) Is there any internal study, article or publication showing the use of ab3110 with success for rat samples staining?

      I'm forward to hearing from you.

      Thanks for your attention.

      Best Regards,

      Answer

      Thank you and you customer for your inquiry.

      1.)I amsorry for this misunderstanding. The sequence of the rat MDM2 can be found on the Swiss Prot website here:

      http://www.uniprot.org/uniprot/D3ZQ36

      What my colleague wanted to say is that there is not much information to be found about the rat proteinand also isoforms are not know so far. But according to Swiss Prot site this protein is not well characterised in rat and is still in the "predicted" status. I up-dated the comment on our datasheet to avoid further confusion.

      The good news is that the immunogen of ab3110 and the rat MDM2 share a 100% homology and therefore the antibody will cross-react. Since this is stated on the datasheet we will guarantee this for your customer.

      2.) We currently do not know of a publication that used ab3110 in rat.

      I hope this information is helpful. Please do not hesitate to contact me again with any further questions.
