Uses for DNA structure-specific recognition protein

Abstract

Methods disclosed herein capitalize on the ability of DNA Structure Specific Recognition Proteins (SSRPs) to bind to genomic lesions formed by chemotherapeutic agents, particularly cisplatin-type agents. Methods are provided for predicting whether an agent that damages DNA will also be cytotoxic, and for predicting whether particular eukaryotic cells will be susceptible to killing by a genotoxic drug. A screening method is provided for identifying new genotoxic drugs that produce SSRP-recognized lesions in DNA. Methods also are provided for sensitizing particular eukaryotic cells to killing by chemotherapeutic agents, particularly cisplatin-type drugs.
