  • 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 specificity
    Expressed in all tissues tested with high levels in thymus.
  • Sequence similarities
    Belongs to the MDM2/MDM4 family.
    Contains 1 RanBP2-type zinc finger.
    Contains 1 RING-type zinc finger.
    Contains 1 SWIB domain.
  • Domain
    Region I is sufficient for binding TP53 and inhibiting its G1 arrest and apoptosis functions. It also binds TP73. Region II contains most of a central acidic region and a putative C4-type zinc finger. The RING finger domain which coordinates two molecules of zinc mediates the heterooligomerization with MDM2.
  • Post-translational
    Ubiquitinated. Deubiquitinated by USP2; leading to stabilize it.

Thank you for your inquiry. The actual size was smaller than the predicted one, the reason can be thought that the post translational modification, e.g. phosphorylation, glycosylation etc. They increase the size of the protein. The 80 kDa band of ab1...
