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.
