Turning a Scorpion Toxin into an Antitumor Miniprotein [PDF]

Journal of the American Chemical Society, 2008
The oncoproteins MDM2 and MDMX negatively regulate the activity and stability of the tumor suppressor protein p53 and are important molecular targets for anticancer therapy. Grafting four residues of p53 critical for MDM2/MDMX binding to the N-terminal alpha-helix of BmBKTx1, a scorpion toxin isolated from the venom of the Asian scorpion Buthus ...
