[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>

== Publication Abstract from PubMed ==
 +
Protein Prp8 interacts with several other spliceosomal proteins, snRNAs, and the pre-mRNA and thereby organizes the active site(s) of the spliceosome. The DEAD-box protein Brr2 and the GTPase Snu114 bind to the Prp8 C terminus, a region where mutations in human Prp8 are linked to the RP13 form of Retinitis pigmentosa. We show crystallographically that the C-terminal domain of yeast Prp8p exhibits a Jab1/MPN-like core known from deubiquitinating enzymes. Insertions and terminal appendices are grafted onto this core, covering a putative isopeptidase center whose metal binding site is additionally impaired. Targeted yeast-two-hybrid analyses show that the RP13-linked region in the C-terminal appendix of human Prp8 is essential for binding of human Brr2 and Snu114, and that RP13 point mutations in this fragment weaken these interactions. We conclude that the expanded Prp8 Jab1/MPN domain represents a pseudoenzyme converted into a protein-protein interaction platform and that dysfunction of this platform underlies Retinitis pigmentosa.
