(tested or 100% immunogen sequence identity)
Synthetic peptide corresponding to aa 177-195 of mouse Mdm2.
Detects murine Mdm2, a nuclear phosphoprotein that controls intracellular levels of the tumor suppressor protein p53 by ubiquitination and subsequent proteasomal degradation. Mdm2 also interacts with the retinoblastoma (RB) protein and E2F-1, to promote G1-S phase transition in the cell cycle. Mdm2 activity is controlled by self-ubiquitination; however activation of the PI3K/PKB pathway leads to phosphorylation of Mdm2 at Ser185, which stabilizes the protein.
