Description

Ribosome profiling (ribo-seq) is a technique that takes advantage of NGS technology to sequence ribosome-protected mRNA fragments and consequently allows the locations of translating ribosomes to be determined at the entire transcriptome level (Ingolia et al., 2009).

For a more detailed description of the protocol, see Ingolia et al. (2012). For reviews on this technique and its applications, please refer to Ingolia (2014) and Michel et al. (2013).

This track displays cumulative ribo-seq data obtained from human cells under different conditions and can be used for the exploration of human genomic loci that are being translated. The values on the y-axis represent the number of ribosome footprint sequence reads at a given position. As of December 2014, the track contains data from 12 studies (see References section for details). Further details about the aggregated track and additional ribo-seq data from these and other studies including data obtained from other organisms can be found at the specialized ribo-seq browser GWIPS-viz.

Methods

For each study used to generate this track, raw fastq files were downloaded from a repository (e.g., NCBI GEO datasets). Cutadapt was used to trim the relevant adapter sequence from the reads, after which reads below 25 nt in length were discarded. The trimmed reads were aligned to ribosomal RNA using Bowtie and aligning reads were discarded. The remaining reads were then aligned to the hg19 (GRCh37) genome assembly using RUM. An offset of 15 nt (to infer the position of the A-site) was added to the most 5' nucleotide coordinate of each uniquely-mapped read.

The alignment files from each of the included studies were merged to generate this aggregate track.

See individual studies at GWIPS-viz for a full description of the methods of data acquisition and processing.
