DBF3, DNA39, RNA8, SLT21, USA2, U4/U6-U5 snRNP complex component PRP8, L000001500, L000003226, YHR165C
Component of U4/U6-U5 snRNP complex; involved in second catalytic step of splicing; participates in spliceosomal assembly through its interaction with U1 snRNA; largest and most evolutionarily conserved protein of the spliceosome; mutations in its human ortholog, PRPF8, cause Retinitis pigmentosa and missplicing in Myelodysplastic syndrome.

Co-localization

Interaction inferred from two proteins that co-localize in the cell by indirect immunofluorescence only when in addition, if one gene is deleted, the other protein becomes mis-localized. Also includes co-dependent association of proteins with promoter DNA in chromatin immunoprecipitation experiments.

Publication

Prp16p, Slu7p, and Prp8p interact with the 3' splice site in two distinct stages during the second catalytic step of pre-mRNA splicing.

Umen JG, Guthrie C

For the second catalytic step of pre-mRNA splicing to occur, a 3' splice site must be selected and juxtaposed with the 5' exon. Four proteins, Prp16p, Slu7p, Prp17p, Prp18p, and an integral spliceosomal protein, Prp8p, are known to be required for the second catalytic step. prp8-101, an allele of PRP8 defective in 3' splice site recognition, exhibits specific genetic interactions ...

Co-fractionation
Co-fractionation

Interaction inferred from the presence of two or more protein subunits in a partially purified protein preparation. If co-fractionation is demonstrated between 3 or more proteins, then add them as a complex.
