Conversion of apoptotic proteins
Compounds that modulate the function of anti-apoptotic proteins such as Bcl-2 and Bcl-X L are identified. These compounds have the ability to convert the activity of Bcl-2-family member proteins from anti-apoptotic to pro-apoptotic. Methods for inducing apoptosis are described, together with methods for identifying molecules that induce apoptosis through interaction with Bcl-2-family members.
1. An isolated compound which binds to Bcl-2 protein and modulates the activity of said Bcl-2 protein in a cell so as to be inductive of apoptosis, without cleaving the Bcl-2 protein, wherein said compound consists of the 69 amino acids between amino acids 467 and 536 of the human TR3 receptor of SEQ ID NO: 3.
2. The compound of claim 1 wherein said compound induces a conformational change in Bcl-2.
3. The compound of claim 1 , wherein the compound comprises at least one D-amino acid.
