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.
This short domain is found at the C-terminus of many helicase proteins, including ATP-dependent rRNA helicase SPB4 from Saccharomyces cerevisiae, which is involved in the biogenesis of 60S ribosomal subunits. SPB4 is organised into four domains: dual ...
This short domain is found at the C-terminus of many helicase proteins, including ATP-dependent rRNA helicase SPB4 from Saccharomyces cerevisiae, which is involved in the biogenesis of 60S ribosomal subunits. SPB4 is organised into four domains: dual RecA domains (Pfam:PF00270 and Pfam:PF00271), a C-terminal extension (CTE, represented by this entry) and a C-terminal tail (Pfam:PF23681). This domain packs closely onto the catalytic core and engages the four nucleotides immediately 5' to those within the RNA binding pocket. It shows a mainly alpha- helical structure [1].
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.
This family includes: archaeal 50S ribosomal protein L18Ae, often referred to as L20e or LX; fungal 60S ribosomal protein L20; and higher eukaryote 60S ribosomal protein L18A.

The RRM motif (a.k.a. RRM, RBD, or RNP domain) is probably diagnostic of an RNA binding protein. RRMs are found in a variety of RNA binding proteins, including various hnRNP proteins, proteins implicated in regulation of alternative splicing, and protein components of snRNPs. The motif also appears in a few single stranded DNA binding proteins. The RRM structure consists of four strands and two helices arranged in an alpha/beta sandwich, with a third helix present during RNA binding in some cases The C-terminal beta strand (4th strand) and final helix are hard to align and have been omitted in the SEED alignment The LA proteins (Swiss:P05455) have an N terminal rrm which is included in the seed. There is a second region towards the C terminus that has some features characteristic of a rrm but does not appear to have the important structural core of a rrm. The LA proteins (Swiss:P05455) are one of the main autoantigens in Systemic lupus erythematosus (SLE), an autoimmune disease.

This entry represents the N-terminal, pre-PUA domain of yeast 60S ribosome subunit biogenesis protein NIP7 and homologues, some uncharacterised proteins from the UPF0113 family and similar sequences from eukaryotes and some archaeal species. NIP7 is required for proper 27S pre-rRNA processing and 60S ribosome subunit assembly. This domain is found associated with Pfam:PF03657.
