Helicases are involved in unwinding nucleic acids. The DEAD box helicases are involved in various aspects of RNA metabolism, including nuclear transcription, pre mRNA splicing, ribosome biogenesis, nucleocytoplasmic transport, translation, RNA decay and organellar gene expression.

PF00271Helicase conserved C-terminal domain (Helicase_C)Helicase conserved C-terminal domainThe Prosite family is restricted to DEAD/H helicases, whereas this domain family is found in a wide variety of helicases and helicase related proteins. It may be that this is not an autonomously folding unit, but an integral part of the helicase.Domain

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].
