Sample GSM6696328 Query DataSets for GSM6696328
Status Public on Feb 07, 2023
Title CAGE_dcp2D_Replicate_1
Sample type SRA
 
Source name Whole cells
Organism Saccharomyces cerevisiae
Characteristics genotype: W303 F2150 (MATa ade2-1 ura3-1 his3-11,15 trp1-1 leu2-3,112 can1-100 dcp2delta::HIS3)
Extracted molecule total RNA
Extraction protocol CAGE libraries were constructed from 5µg of total RNA isolated from two biological replicates of each strain using the nAnT-iCAGE protocol (Murata et al. 2014) by DNAFORM in Yokohama, Japan. After first strand cDNAs were transcribed to the 5’ end of capped RNAs, cap structure of mRNA was chemically biotinylated to allow streptavidin capture, RNase1 digested, captured using avidin magnetic beads and attached to CAGE “barcode” tags. Each CAGE library used linkers with specific barcodes and was sequenced using Illumina NextSeq 
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection CAGE
Instrument model Illumina NextSeq 500
 
Data processing As described earlier (Martin-Marcos et al. 2017), Illumina sequencing reads were trimmed to remove the constant adapter sequence, mixed sample sequences were separated by the sample barcodes followed by removal of PCR duplicates using a custom Python (3.7) script. The sequences aligned to yeast non-coding RNAs were removed using bowtie (Langmead et al., 2009) and non-rRNA reads (unaligned reads) were then mapped to the S. cerevisiae genome (R64-1-1 S288C Saccer3 Genome Assembly) using TopHat (Trapnell et al., 2009). Only uniquely mapped reads from the final genomic alignment were used for subsequent analyses. Normalized wiggle files and reads counts are generated with RiboSeq tools (https://github.com/hzhanghenry/RiboProR). For RNA-seq, the same protocol mentioned above for ribo-seq analysis was followed.
The sequenced CAGE reads of each sample were aligned to the reference genome of S. cerevisiae S288c (Assembly version: sacCer3) using HISAT2. CAGE reads mapped to rRNA genes were identified using rRNAdust (http://fantom.gsc.riken.jp/5/sstar/Protocols:rRNAdust), and were excluded from subsequent TSS analyses. CAGE reads with a mapping quality score (MAPQ) > 20 were considered uniquely mapped reads and were used for subsequent analyses. CAGE signals of biological replicates were then merged as a single sample. The transcription abundance of each TSS was quantified as the numbers of CAGE tags/reads supporting the TSS per million mapped reads (TPM). For RNA-Seq samples in parallel with CAGE-Seq, Fastq files after passing the QC and the adapter content check they were mapped to yeast genome (sacCer3) with STAR aligner, then PCR duplicates were removed by samtools.
Assembly: sacCer3
Supplementary files format and content: Processed data (csv) files contain raw reads for each file. For ribosome profiling and parallel RNA-Sequencing, Raw_counts_Ribo (Ribo-sequencing) and Raw_counts_RNA (RNA-sequencing), each file contains five columns providing: systemmatic gene name (Gene_ID), total reads (trx), reads in CDS, reads in 5' UTR and reads in 3' UTR. Foe CAGE-sequencing and parallel RNA-Sequencing, each file contains two columns providing: systemmatic gene name (Gene_ID), total reads.
