Anti-MDM4 Antibody, clone 7A8

MDM4 (sometimes referred to as MDMX) is a member of the MDM family proteins. It is known to inhibit p53 and p73 mediated cell cycle arrest and apoptosis. MDM4 is amplified or overexpressed in 10-20% of tumors and 65% of retinoblastomas. The full-length protein has significant homology to MDM2 and can also bind to and inhibit p53. In both MDM2 and MDM4, this interaction with p53 occurs via a binding domain located in the N-terminal region of the protein. Other similar domains include the C-terminal RING finger motif. Although these proteins share similar domains, MDM2 and MDM4 are non-redundant p53 inhibitors, since normal levels of either protein does not compensate for the loss of the other. Recent evidence suggests complementary activities for these proteins with MDM4 regulating p53 activity, and MDM2 playing a key role in p53 stability.

~ 80/27 kDa Observed. There are multiple forms for MDM4. Up to 7 different variants have been reported. Full legth of MDM4 is ~80kDa The short form of MDM4 (MDM4-S) migrates at approximately 17 and 27kDa (R. Rallapalli, G. Strachan, B. Cho, W. Mercer‡, and DJ. Hall, 1999, A Novel MDMX Transcript, THE JOURNAL OF BIOLOGICAL CHEMISTRY, 274(12), 8299–8308)
