This study introduces CAGEr, an R package for analyzing Cap analysis of gene expression (CAGE) data. CAGEr enhances the use of CAGE data for promoter analysis by providing tools for differential transcription start site (TSS) usage and promoter dynamics.
Area of Science:
- Genomics
- Transcriptomics
- Bioinformatics
Background:
- Cap analysis of gene expression (CAGE) offers high-resolution transcriptome analysis but is underutilized in promoter studies.
- Existing CAGE data lacks accessible tools for manipulation and integration with other genomic data types.
Purpose of the Study:
- To present CAGEr, a comprehensive R package toolbox for CAGE data analysis.
- To enable efficient manipulation and integration of CAGE data for promoter analysis.
- To increase accessibility of context-specific transcription start site (TSS) data.
Main Methods:
- Development of an R implementation (CAGEr) for novel CAGE data analysis methods.
- Integration of CAGE data processing, differential TSS usage analysis, and promoterome mining.
- Provision of access to aggregated CAGE datasets and the FANTOM5 resource within R.
Main Results:
- CAGEr provides a comprehensive toolbox for CAGE data analysis on a common platform.
- The package facilitates analysis of differential TSS usage and promoter dynamics.
- Direct access to extensive TSS data from CAGE datasets and FANTOM5 is now available within R.
Conclusions:
- CAGEr significantly enhances the utility of CAGE data for promoter analysis.
- The package democratizes access to precise, context-specific TSS information for integrative genomics.
- CAGEr is freely available from Bioconductor, promoting wider adoption in research.
