Screening for peptides inhibiting PP1c binding to BcI-2, BCL-XL and BCL-W proteins

摘要

The invention relates to methods for identifying novel PP1-interacting polypeptides and proteins, compounds which are able to inhibit the binding of PP1c to certain factors naturally interacting with it, especially proteins of the Bcl-2 family (such as Bcl-x L and Bcl-w), and pharmaceutical compositions comprising the same. The invention is based on the identification of a new PP1- binding motif having the sequence FXX[RK]X[RK], wherein X is any amino acid.
