(Submitter supplied) Introns in pre-mRNAs must be spliced out prior to their translation. During splicing, introns are removed in the form of a lariat, in which the 5' end is linked to the 2' hydroxyl of an internal adenosine. Lariat degradation is initiated by an 2'-5' phosphodiester-specific RNA endonuclease which debranches these lariat RNAs to linear form. Deletion of the debranching enzyme is yeast results in the accumulation of lariat introns. more...

(Submitter supplied) The role of many splicing factors in pre-mRNA splicing and the involvement of these factors in the processing of specific transcripts have often been defined through the analysis of loss of function mutants in vivo. Here we show that inactivating the nonsense mediated mRNA decay (NMD) results in an enhancement of splicing phenotypes associated with several splicing factors mutations. Tiling microarrays showed that inactivation of the NMD factor Upf1p in the prp17Δ and prp18Δ mutant strains reveals a larger spectrum of splicing defects than what is observed in the single mutants, including new transcripts previously shown unaffected by Prp17p or Prp18p inactivation. more...

(Submitter supplied) Using RNA-Seq analysis of nonsense-mediated mRNA decay (NMD) mutant strains, we show that many Saccharomyces cerevisiae intron-containing genes exhibit usage of alternative splice sites, but most transcripts generated by splicing from these sites are non-functional because they introduce premature termination codons leading to transcript degradation by NMD. Analysis of splicing mutants combined with NMD inactivation revealed the role of specific splicing factors in governing the use of these alternative splice sites and identified novel functions for Prp17p in enhancing the use of branchpoint-proximal upstream 3’ splice sites and for Prp18p in suppressing the usage of a non-canonical AUG 3’-splice site. more...

(Submitter supplied) While the core splicing machinery is highly conserved between budding yeast and mammals, the absence of alternative splicing in Saccharomyces cerevisiae raises the fundamental question of why introns have been retained in ~5% of the 6,000 genes. Because Ribosomal Protein-encoding Genes (RPGs) are highly over-represented in the set of intron-containing genes, we tested the hypothesis that splicing of these transcripts would be regulated under conditions where translation is impaired. more...

(Submitter supplied) During meiosis in yeast, global splicing efficiency increases. The mechanism for this is relief of competition for the splicing machinery by repression of intron-containing ribosomal protein genes (RPGs). Repression of RPGs with rapamycin also increases splicing efficiency in vegetative cells. Reducing levels of an RPG-dedicated transcription factor globally improves splicing and suppresses the temperature-sensitive growth defect of a spliceosome mutation. more...

(Submitter supplied) In eukaryotes, a dynamic ribonucleic protein machine known as the spliceosome catalyzes the removal of introns from pre-messenger RNA (pre-mRNA). Recent studies show the process of RNA-synthesis and RNA-processing to be spatio-temporally coordinated, indicating that RNA splicing takes place in the context of chromatin. H2A.Z is a highly conserved histone variant of the canonical histone H2A. In S. cerevisiae, H2A.Z is deposited into chromatin by the SWR1-complex, is found near the 5’ ends of protein-coding genes, and has been implicated in transcription regulation. more...

(Submitter supplied) Changes in RNA levels during osmotic stress were investigated. Total RNA was extracted from a wild-type yeast strain before and after treatment with 0.4 M NaCl and the corresponding cDNAs were hybridazed on Tiling arrays. In particular, for all the intron-containing genes, the changes in the levels of intron signal in stressed cells related to the intron signal in the non-stressed cells, and the changes in the levels of exon signal in stresses cells related to the exon signal in non-stressed cells were investigated. more...

(Submitter supplied) Gene expression in Eukaryotic cells is profoundly shaped by the post-transcriptional processing of mRNAs, including the splicing of introns in the nucleus and both nuclear and cytoplasmic degradation pathways. Here we report the use of a splicing isoform specific microarray platform to investigate the effects of a host of diverse stress conditions on both splicing pre-mRNA fate. Interestingly, We find that diverse stresses cause distinct patterns of changes at the level of pre- mRNA processing. more...
