This domain is found at the N-terminal end of Exosome complex component CSL4 from Saccharomyces cerevisiae, a non-catalytic component of the RNA exosome complex which has 3'->5' exoribonuclease activity and participates in a multitude of cellular RNA processing and degradation events [1-4].
This family of proteins are components of the exosome 3'->5' exoribonuclease complex. The exosome mediates degradation of unstable mRNAs that contain AU-rich elements (AREs) within their 3' untranslated regions [1].

This domain is responsible for the 3'-5' exonuclease proofreading activity of E. coli DNA polymerase I (polI) and other enzymes, it catalyses the hydrolysis of unpaired or mismatched nucleotides. This domain consists of the amino-terminal half of the Klenow fragment in E. coli polI it is also found in the Werner syndrome helicase (WRN), focus forming activity 1 protein (FFA-1) and ribonuclease D (RNase D). Werner syndrome is a human genetic disorder causing premature aging; the WRN protein has helicase activity in the 3'-5' direction [4,5]. The FFA-1 protein is required for formation of a replication foci and also has helicase activity; it is a homologue of the WRN protein [3]. RNase D is a 3'-5' exonuclease involved in tRNA processing. Also found in this family is the autoantigen PM/Scl thought to be involved in polymyositis-scleroderma overlap syndrome.

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.

Exosome RNA helicase MTR4 is a conserved RNA helicase that functions together with the nuclear exosome and it is involved in processing of structured RNAs, including snRNAs and snoRNAs. 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].

This is the N-terminal domain of Rrp40 of the exosome complex present in Saccharomyces cerevisiae. The RNA exosome complex is responsible for degrading RNA molecules in the 3' to 5' direction. Rrp40 is a 'cap' protein and binds the RNase PH barrel on the opposite side from the S1/KH ring. The N-terminal domain of Rrp44 forms a long beta-hairpin that is wedged in between Rrp41-Rrp42 and approaches the N terminus of the cap protein Rrp4 [1]. This domain adopts a beta- sandwich hybrid structure.
