A New Approach for p53 Activation in the Treatment of Cancer (Yissum)
Highlights:
p53, the most important tumour suppressor protein in the cell, is a homotetrameric protein that has a pivotal role in the cellular anti cancer defense mechanism.
p53 is active as a tetramer: the tetramer binds DNA much tighter than the monomer / dimer and is retained in the nucleus while the monomers / dimers are exported and degraded.
Molecules that bind specifically to tetrameric p53 C-terminal domain can potentially activate p53 by stabilizing the active tetramer.
Our Innovation:
We developed peptides that bind preferably to tetrameric p53 through its C-terminal domain and stabilize it.
Key Features:
These peptides may form a basis for developing small anti cancer molecules that activate p53 by shifting its oligomerization equilibrium towards the active tetramer resulting in an increase in the concentration of active p53 and inducing apoptosis of cancer cells.
