BioAssay: AID 588623

qHTS for Inhibitors of Polymerase Iota: Summary

DNA polymerases, such as Pol iota, are specifically involved in DNA repair. Pol iota specifically plays an important role in translesion synthesis, where the normal high-fidelity DNA polymerases cannot proceed and DNA synthesis stalls. It has been reported that human pol iota may be upregulated in a number of human cancers and specifically during the progression of breast cancer, indicating that more ..

Description:
DNA polymerases, such as Pol iota, are specifically involved in DNA repair. Pol iota specifically plays an important role in translesion synthesis, where the normal high-fidelity DNA polymerases cannot proceed and DNA synthesis stalls. It has been reported that human pol iota may be upregulated in a number of human cancers and specifically during the progression of breast cancer, indicating that pol iota's activities within normal living cells must be tightly regulated. Thus, while pol eta's (and most likely iota's) normal function is to protect humans against the deleterious consequences of DNA damage, under certain conditions they can have deleterious effects on human health. As a consequence, we propose to utilize a high throughput replication assay to identify small molecule inhibitors of pol iota.

In a collaboration between the National Institute of Child Health & Human Development (NICHD) and NIH Chemical Genomics Center, a high-throughput, fluorescent screen was developed to screen the NIH Molecular Libraries Small Molecule Repository (MLSMR). This screen is used to identify inhibitors of pol iota.
