== Function ==
[[https://www.uniprot.org/uniprot/PRP8_YEAST PRP8_YEAST]] Required for pre-spliceosome formation, which is the first step of pre-mRNA splicing. This protein is associated with snRNP U5. Has a role in branch site-3' splice site selection. Associates with the branch site-3' splice 3'-exon region. Also has a role in cell cycle.<ref>PMID:2835658</ref> <ref>PMID:9150140</ref> <ref>PMID:12773561</ref> <ref>PMID:18779563</ref>  [[https://www.uniprot.org/uniprot/AAR2_YEAST AAR2_YEAST]] Involved in splicing pre-mRNA of the A1 cistron and other genes that are important for cell growth.

== Publication Abstract from PubMed ==
Crystallographic fragment screening (CFS) provides excellent starting points for projects concerned with drug discovery or biochemical tool compound development. One of the fundamental prerequisites for effective CFS is the availability of a versatile fragment library. Here, we report on the assembly of the 1,103-compound F2X-Universal Library and its 96-compound sub-selection, the F2X-Entry Screen. Both represent the available fragment chemistry and are highly diverse in terms of their 3D-pharmacophore variations. Validation of the F2X-Entry Screen in CFS campaigns using endothiapepsin and the Aar2/RNaseH complex yielded hit rates of 30% and 21%, respectively, and revealed versatile binding sites. Dry presentation of the libraries allows CFS campaigns to be carried out with or without the co-solvent DMSO present. Most of the hits in our validation campaigns could be reproduced also in the absence of DMSO. Consequently, CFS can be carried out more efficiently and for a wider range of conditions and targets.
