Transcriptome analysis of budding yeast strains manipulated in RPL22A and RPL22B genes

ABSTRACT: Most Saccharomyces cerevisiae ribosomal protein genes (RPGs) are present as two paralogous copies that emerged during a whole genome duplication. The preservation of two copies of the same gene during the past ~100 million years enabled diversification of the regulation of their expression, and also partially of their functional properties. One example of such paralogous genes are RPL22A and RPL22B that are asymmetrically expressed and their protein sequences represent one of the most divergent pairs among budding yeast RPG paralogs. It was shown that introns in the RPL22A and RPL22B genes are important for regulation of their expression levels. To investigate functional differences between RPL22A and RPL22B we performed RNA-seq analysis of strains with complete deletions of either RPL22A or RPL22B, and also of strains with intron deletions in the RPL22 genes, in comparison with a wild-type strain. Cells were grown to mid-exponential phase in the rich YPAD medium. 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.

RNA-seq analysis of budding yeast wild type (BY4741) and prp45(1-169) mutant

Project 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.

RNA-seq analysis of the budding yeast rad6 strain and prp45(1-169) rad6 double mutant strain

Project description:Prp45 is a budding yeast NineTeen-Complex associated factor, which plays a role in pre-mRNA splicing. Because its human ortholog, SNW1/SKIP, is known to functionally and physically interact with factors involved in transcription elongation and chromatin modifications, it was suggested to be one of the coupling factors which functionally connect splicing and transcription. To determine whether the yeast Prp45 has this function as well we tested genetic interactions between prp45(1-169) allele and deletions of histone modifiers and transcription elongation regulators. RNA-seq analysis was performed to address the changes in transcription and/or splicing in strains deleted in rad6, a kinase phosphorylating serine 2 of the C-terminal domain of RNA Polymerase II and an E2 enzyme for H2BK123 monoubiquitination, respectively, and the corresponding double mutant with prp45(1-169). 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.

RNA-seq analysis of the budding yeast prp45(1-169) strain (a scarless truncation)

Project description:Prp45 is a budding yeast NineTeen-Complex associated factor, which plays a role in pre-mRNA splicing. prp45(1-169) is a temperature-sensitive truncation allele expressing only the first 169 amino acids (the full-length protein consists of 379 amino acids). RNA-seq analysis was performed to determine changes in transcription and splicing in cells with prp45(1-169) allele prepared by the CRISPR/Cas9 method as a scarless truncation, i.e. with no tags and with preserved endogenous 3' UTR. 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.

SuhB associates with Nus factors to facilitate 30S ribosome biogenesis in Escherichia coli

Project description:This experiment consists of two studies. The first where two independent biological replicates of MG1655, MG1655 thyA suhB::thyA and MG1655 thyA nusB::thyA were each grown in LB to mid-exponential phase. RNA-seq and associated data analysis were performed as described previously (Stringer et al., 2014. PMID 24272778). The second where five cultures of MG1655 thyA suhB::thyA were grown overnight from single colonies at 37 C in LB. 5 L of each overnight culture was spread on LB agar and incubated at 30 C, the non-permissive temperature for suhB mutants. One suppressor mutant colony was selected from each plate. rnc was PCR amplified from colonies using oligonucleotides JW836-JW837, and the PCR products were sequenced to identify the presence, if any, of suppressor mutations. Genomic DNA from a strain with wild-type rnc was prepared using a DNeasy Blood and Tissue Kit (Qiagen). A DNA library was prepared using a Nextera kit (Illumina). The library was sequenced (paired-end reads) using an Illumina MiSeq instrument.
