This domain is found in U4/U6 and U4/U5/U6-small nuclear ribonucleoprotein Prp3, part of the tri-RNA complex that form the spliceosome. Prp3 plays a key role in the recognition of the snRNA duplex. The pre-mRNA processing factor 3 (PRP3) domain, responsible for the binding to stem II of the snRNA duplex, is highly conserved among eukaryotes and is found N-terminal to Pfam:PF06544 [3,4]. The human PRP3 has been implicated in autosomal retinitis pigmentosa [2].	Domain

This domain is found at the C-terminal end of U4/U6 and U4/U5/U6- small nuclear ribonucleoprotein Prp3, part of the tri-RNA complex that form the spliceosome. Prp3 plays a key role in the recognition of the snRNA duplex. This binding domain, highly conserved among eukaryotes, interacts with the 3' end of U6 snRNA. It adopts a ferredoxin-like fold, showing a five-stranded mixed beta-sheet with three alpha-helices, two of them running parallel to the beta-strands on one side of the sheet and one on the other. This fold is extended with a long beta-hairpin, an extra beta-strand, an helix and a final loop at the C terminus. It is located C-terminal to Pfam:PF08572 [1-4].	Domain

The U1, U2, U4/U6, and U5 small nuclear ribonucleoprotein particles (snRNPs) involved in pre-mRNA splicing contain seven Sm proteins (B/B', D1, D2, D3, E, F and G) in common, which assemble around the Sm site present in four of the major spliceosomal small nuclear RNAs. The U6 snRNP binds to the LSM (Like Sm) proteins [3]. Sm proteins are also found in archaebacteria, which do not have any splicing apparatus suggesting a more general role for Sm proteins. All Sm proteins contain a common sequence motif in two segments, Sm1 and Sm2, separated by a short variable linker. This family also includes the bacterial Hfq (host factor Q) proteins.

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 large RNA-protein complex of the spliceosome catalyses pre-mRNA splicing. One of the most conserved core proteins is PrP8 which occupies a central position in the catalytic core of the spliceosome, and has been implicated in several crucial molecular rearrangements that occur there, and has recently come under the spotlight for its role in the inherited human disease, Retinitis Pigmentosa [1]. The RNA-recognition motif of PrP8 is highly conserved and provides a possible RNA binding centre for the 5-prime SS, BP, or 3-prime SS of pre-mRNA which are known to contact with Prp8. The most conserved regions of an RRM are defined as the RNP1 and RNP2 sequences. Recognition of RNA targets can also be modulated by a number of other factors, most notably the two loops beta1-alpha1, beta2-beta3 and the amino acid residues C-terminal to the RNP2 domain [2].
