Methods and compositions relating to promoter regulation by MUC1 and KLF proteins
First Claim
1. A method of identifying a compound that inhibits the binding of MUC1 to a kruppel-like factor (KLF), the method comprising:
- (a) contacting a MUC1 peptide segment comprising the MUC1 cytoplasmic domain (MUC1-CD) comprising SEQ ID NO;
3 with a KLF4 peptide segment comprising SEQ ID NO;
7 in the presence of a candidate compound; and
(b) determining whether the candidate compound inhibits binding of the MUC1 peptide segment to the KLF peptide segment.

Abstract
This invention relates to regulation of cell signaling, cell growth, and more particularly to the regulation of cancer or inflammatory cell growth and/or activation. The invention provides methods of, and compositions useful for, inhibiting interactions between MUC1 and a kruppel-like factor (KLF), method of inhibiting interactions between a KLF protein and the p53 promoter, methods of inhibiting the interaction between MUC1 and the p53 promoter, methods of increasing p53 activity, and methods of increasing histone acetylation. The invention also provides screening methods for identifying compounds that inhibit the aforementioned interactions. Pharmaceutical compositions containing the identified compounds can be useful in treating cancers and inflammatory conditions.
