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

It also plays a role in nuclear RNA surveillance pathways involving the so-called TRAMP complex [1,2]. It contains an arch domain, required for proper 5.8S rRNA processing, and appears to function independently of canonical helicase activity [3]. The arch domain comprises an helical stalk/elbow that flanks a KOW module which adopts a beta-barrel fold. This entry represents the helical stalk found at the N-terminal of KOW beta-barrel from MTR4 [1-3]. This entry also includes Ski2-like helicases which have an overall similar structure to MTR4 proteins. However, Ski2 from yeast does not have the KOW motif and the beta-barrel is tightly packed against the helical stalk [3].
