|Other Names||Protein Mdm4, Double minute 4 protein, Mdm2-like p53-binding protein, Protein Mdmx, p53-binding protein Mdm4, MDM4, MDMX|
|Target/Specificity||The synthetic peptide sequence used to generate the antibody AP13861c was selected from the Center region of MDM4. A 10 to 100 fold molar excess to antibody is recommended. Precise conditions should be optimized for a particular assay.|
|Format||Synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml DI water for a final concentration of 1 mg/ml.|
|Storage||Maintain refrigerated at 2-8°C for up to 6 months. For long term storage store at -20°C.|
|Precautions||This product is for research use only. Not for use in diagnostic or therapeutic procedures.|
|Function||Inhibits p53/TP53- and TP73/p73-mediated cell cycle arrest and apoptosis by binding its transcriptional activation domain. Inhibits degradation of MDM2. Can reverse MDM2-targeted degradation of TP53 while maintaining suppression of TP53 transactivation and apoptotic functions.|
|Tissue Location||Expressed in all tissues tested with high levels in thymus|

The human MDM4 gene, which plays a role in apoptosis,encodes a 490-amino acid protein containing a RING finger domainand a putative nuclear localization signal. The MDM4 putativenuclear localization signal, which all Mdm proteins contain, islocated in the C-terminal region of the protein. The mRNA isexpressed at a high level in thymus and at lower levels in allother tissues tested. MDM4 protein produced by in vitro translationinteracts with p53 via a binding domain located in the N-terminalregion of the MDM4 protein. MDM4 shows significant structuralsimilarity to p53-binding protein MDM2. Two transcript variants,one protein-coding and the other likely not to be protein-coding,have been found for this gene.
