Abstract
A domain of Bcl-2 that suppresses apoptosis by allowing cell survival permits cell proliferation when mutated. The wild type domain includes amino acid residues 51 to 97 (SEQ ID NO:13) of Bcl-2. Peptides including the domain and nucleotides encoding the domain are useful in molecular screening of human tumors for the presence of mutations that allow proliferation of cells that were otherwise marked for apoptosis. The peptides are also useful to screen for proteins that play a role in the modulation of cellular proliferation.
Claims6
An isolated antibody that specifically binds to the AP domain of Bcl-2 or a fragment thereof, wherein said AP domain or fragment thereof is a Bcl-2 protein comprising residues 51 to any of 85-97 (SEQ ID NOS:
- 1-13) or a fragment thereof that contains at least one of Ser residue 51, Pro residue 57, Ser residue 62, Thr and Ser residues 69 and 70, Thr residue 74, and Pro residue 75, wherein said fragment exhibits full or partial anti-proliferation activity of the AP domain.
