Description
Prp45 is a budding yeast NineTeen-Complex associated factor, which plays a role in pre-mRNA splicing. In addition to its documented involvement in the second step of splicing, here we show that it is important in the early stages of co-transcriptional spliceosome assembly as well. To determine the overall splicing efficiency of prp45 mutant cells and to reveal how the efficiency depends on the sequences which define introns (whether they are consensual or non-consensual), we performed RNA-seq analysis of prp45(1-169) and corresponding wild-type cells (two biological replicates each). Total RNA was isolated by combining phenol-chlorophorm extraction with MasterPure Yeast RNA Purification Kit (Epicentre). Ribodepletion, library preparation and sequencing were performed by BGI Genomics.
