Description - FANTOM5
Regulated transcription controls the diversity, developmental pathways, and spatial organization of the hundreds of cell types that make up a mammal. In FANTOM5 ( http://fantom.gsc.riken.jp/5/ ), we mapped transcription start sites (TSS) and their usage in human and mouse primary cells, cell lines and tissues to produce a comprehensive overview of gene expression across the human body by using single molecule sequencing. This datahub is set up to provide the TSS activities in individual biological states and the identified regions. Please visit the web site for further data exploration and with details.
Individual biological states are profiled by HeliScopeCAGE, which is a variation of CAGE (Cap Analysis Gene Expression) protocol based on a single molecule sequencer. The standard protocol requiring 5 µg of total RNA as a starting material is referred as hCAGE, and an optimized version for lower quantity (~ 100 ng) is referred as LQhCAGE (Kanamori-Katyama et al. 2011).
We mapped transcription start sites (TSSs) and their usage in human and mouse primary cells, cell lines and tissues to produce a comprehensive overview of mammalian gene expression across the human body.
5′-end of the mapped CAGE reads are counted at a single base pair resolution (CTSS, CAGE tag starting sites) on the genomic coordinates, which represent TSS activities in the sample. Individual samples shown in "TSS activity" tracks are grouped as below.
- Primary cell
- Cell Line
- Time course
TSS peaks and enhancers
TSS (CAGE) peaks across the panel of the biological states (samples) are identified by DPI (decomposition based peak identification, Forrest et al 2014), where each of the peaks consists of neighboring and related TSSs. The peaks are used as anchor to define promoters and as unit of promoter-level expression analysis. Two subsets of the peaks are defined based on evidence of read counts, depending on scopes of subsequent analyses, and the first subset (referred as robust set of the peaks, thresholded for expression analysis is shown as TSS peaks. They are named as "p#@GENE_SYMBOL" if associated with 5'-end of known genes, or "p@CHROM:START..END,STRAND" otherwise. The CAGE data is also used to produce an atlas of active, in vivo-transcribed enhancers (Andersson et al. 2014). The summary tracks consist of the TSS (CAGE) peaks, the enhancers, and summary profiles of TSS activities (total and maximum values). The summary track consists of the following tracks.
- TSS (CAGE) peaks
- TSS summary profiles
- Total counts and TPM (tags per million) in all the samples
- Maximum counts and TPM among the samples
A set of enhancers consist of the ones identified by Andersson et al. and the ones by Hirabayashi et al.
