DNA polymerase theta (Pol Theta, encoded the POLQ gene) is one of ~15 DNA polymerases in the human genome. PolQ is distinct among human DNA polymerases, exhibiting not only a C-terminal DNA polymerase domain but also an N-terminal domain exhibiting similarity and motifs typical of superfamily 2 (SF2) helicases [1]. This entry corresponds to the helical domain [1].	Domain

This entry describes the N-terminal domain of unknown function of DNA polymerase theta subunit (PolQ) majoritarily from fungal and and yeast proteins. Structural predictions suggest that this family adopts Helix-Helix-Helix (HHH) motifs. Proteins containing HHH motifs are typically associated with DNA-binding functions. These structural elements are often found in enzymes involved in DNA metabolism, such as DNA polymerases and helicases [1,2].	Domain
