Members of this family include the DEAD and DEAH box helicases. 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.
The 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.

THO is a multi-protein complex involved in the formation of messenger ribonuclear particles (mRNPs) by coupling transcription with mRNA processing and export. Some studies show that Tho1, like Sub2, can assemble onto the nascent mRNA during transcription and that Tho1 and Sub2 can provide alternative pathways for mRNP biogenesis in the absence of a functional THO complex. This is the C-terminal domain found in Tho1 and MOS11 proteins. The C-terminal region of Tho1 from Saccharomyces cerevisiae, adopts a helical fold similar to that of the WHEP RNA-binding domains of metazoan aminoacyl-tRNA synthetases [1].
