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 family includes: Ribosomal L7A from metazoa, Ribosomal L8-A and L8-B from fungi, 30S ribosomal protein HS6 from archaebacteria, 40S ribosomal protein S12 from eukaryotes, Ribosomal protein L30 from eukaryotes and archaebacteria. Gadd45 and MyD11 ...

This family contains a central domain Pfam:PF00013, hence the amino and carboxyl terminal domains are stored separately. This is a minimal carboxyl-terminal domain. Some are much longer.
This domain contains a P-loop motif, also found in several other families such as Pfam:PF00071, Pfam:PF00025 and Pfam:PF00063. Elongation factor Tu consists of three structural domains, this plus two C-terminal beta barrel domains.
Members of this family, which are found in the initiation factors eIF2 and EF-Tu, adopt a structure consisting of a beta barrel with Greek key topology. They are required for formation of the ternary complex with GTP and initiator tRNA [1].
This domain is found N-terminal in the homologues of ATP-dependent RNA helicase DDX60 (also known as DEAD-box RNA helicase). This helicase binds ssRNA, dsRNA and dsDNA and can promote the binding of RIGI to dsRNA. DDX60 is non-essential in mammals [1 ...
This domain is found N-terminal in the homologues of ATP-dependent RNA helicase DDX60 (also known as DEAD-box RNA helicase). This helicase binds ssRNA, dsRNA and dsDNA and can promote the binding of RIGI to dsRNA. DDX60 is non-essential in mammals [1] but it is required for the cell fitness in kinetoplastids and trypanosomatids and plays a specific role in translation initiation in these parasites [2]. In Trypanosoma cruzi, k-DDX60 binds both to the head and the body of the 40S ribosome subunit. It is also involved in the stabilization of the 43S PIC and the remodeling of the 43S PIC mRNA channel [2]. The domain represented by this entry adopts a globular structure with a significant structural similarity to PIN domains.
