Background of MDMX

Protein Mdm4 is a protein that in humans is encoded by the MDM4 gene. This gene encodes a nuclear protein that contains a p53 binding domain at the N-terminus and a RING finger domain at the C-terminus, and shows structural similarity to p53-binding protein MDM2. Both proteins bind the p53 tumor suppressor protein and inhibit its activity, and have been shown to be overexpressed in a variety of human cancers. However, unlike MDM2 which degrades p53, this protein inhibits p53 by binding its transcriptional activation domain. This protein also interacts with MDM2 protein via the RING finger domain, and inhibits the latter's degradation. So this protein can reverse MDM2-targeted degradation of p53, while maintaining suppression of p53 transactivation and apoptotic functions. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene.

We are currently using anti-MDMX/MDM4 antibody PB9872 for human tissue, and we are content with the IHC results. The species of reactivity given in the datasheet says human, mouse. Is it true that the antibody can work on canine tissues as well?

S. Anderson

Verified customer

Asked: 2019-09-05


The anti-MDMX/MDM4 antibody (PB9872) has not been tested for cross reactivity specifically with canine tissues, but there is a good chance of cross reactivity. We have an innovator award program that if you test this antibody and show it works in canine you can get your next antibody for free. Please contact me if I can help you with anything.

Would anti-MDMX/MDM4 antibody PB9872 work on primate WB with gastric mucosa?

Verified Customer

Verified customer

Asked: 2019-08-07


Our lab technicians have not validated anti-MDMX/MDM4 antibody PB9872 on primate. You can run a BLAST between primate and the immunogen sequence of anti-MDMX/MDM4 antibody PB9872 to see if they may cross-react. If the sequence homology is close, then you can perform a pilot test. Keep in mind that since we have not validated primate samples, this use of the antibody is not covered by our guarantee. However we have an innovator award program that if you test this antibody and show it works in primate gastric mucosa in WB, you can get your next antibody for free.
