1. A method of identifying a compound that inhibits the binding of MUC1 to a BH3-containing proapoptotic protein, the method comprising:
- (a) contacting a MUC1 reagent comprising the cytoplasmic domain of MUC1 with a MUC1-binding BH3-containing proapoptotic protein or a MUC1-binding fragment thereof in the presence of a candidate compound; and
(b) determining whether the candidate compound inhibits binding of the MUC1 reagent to the BH3-containing proapoptotic protein or the fragment thereof.
