DNA polymerase theta belongs to the A family of DNA polymerases and plays a key role in DNA repair and damage tolerance, including double-strand break repair and DNA translesion synthesis. Pol theta is often overexpressed in cancer cells and promotes their resistance to chemotherapeutic agents. In this review, we discuss unique biochemical properties and structural features of Pol theta, its multiple roles in protection of genome stability and the potential of Pol theta as a target for cancer treatment.
