METHODS AND COMPOSITIONS FOR MODULATING P53 TRANSCRIPTION FACTOR

摘要

This invention provides novel p53 modulatory polypeptides. The invention also provides methods for screening modulators of p53. The methods comprise first screening test agents for modulators of a p53-modulatory polypeptide and then further screening the identified modulating agents for modulators of p53. The invention further provides methods and pharmaceutical compositions for modulating p53 bioactivities in a cell and for treating diseases and conditions mediated by abnormal cellular proliferation.
