total RNA |
Extraction protocol |
After the last washing round the protein-RNA adducts were subjected to RNA fragmentation on the beads, using RNA fragmentation reagent (Ambion) at 94C for exactly 5min in a thermocycler, followed by 1min incubation on ice and then quenched by fragmentation stop solution (Ambion). The fragmented RNA was then purified by ethanol precipitation followed by Trizol (Invitrogen) RNA extraction and used for library preparation.

Data processing |
The 'Make Transcriptome' application from open source USeq package (Utah Bioinformatics Shared Resource Center) was used to build the 'transcriptome index file' to include the different combinations of the splicing events for genes with multiple exons. The commercial "Novoalign" package (Novocraft) was used for sequence alignments with options to allow mismatches, reporting 18bp or larger inserts and reporting all the reads mapped to the repeats and generating SAM formatted alignment files. The 'RNASeq' application of the USeq package was used for assessment of the enriched/over-expressed transcripts using SAM files as input. The 'RNASeq' application of the USeq package was used to generate the BAM/BAI files, from SAM alignments input files, for visualization of the mapped reads. The Integrative genomics viewer (IGV) was used to visualize the alignment files and inspect the mapped reads at base pair resolution. The 'mpileup2cns" function of VarScan package (Washington University) was used to find the significant C>G tranversion sites to report as candidate m5C-RMT target sites.
