Research Abstract

Human DNA polymerase eta (Polη) is the responsible gene product of xeroderma pigmentosum variant, a cancer-prone genetic disorder, and protects cells from cell death or carcinogenesis by catalyzing accurate translesion DNA synthesis (TLS). During this project, we showed that Polη has mutagenic properties depending on DNA damages and situations. We have also identified novel protein-protein interactions and post-translational modifications of Polη and related proteins which could be important for regulating TLS in human cells.
