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.

Synthetic Lethality

A genetic interaction is inferred when mutations or deletions in separate genes, each of which alone causes a minimal phenotype, result in lethality when combined in the same cell under a given condition.

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 ...
