RNA-binding protein motif analysis
Transite is a computational method that allows comprehensive analysis of the regulatory role of RNA-binding proteins in various cellular processes by leveraging preexisting gene expression data and current knowledge of binding preferences of RNA-binding proteins.
Transite and the Transite website were developed in R and C++, using devtools to streamline package development, Travis CI as continuous integration service, Git for version control, roxygen2 for documentation, ggplot2 for visualization, Rcpp for C++ integration, Shiny as web framework, rmarkdown and knitr to generate analysis reports, and dplyr for data wrangling.
Transite is a tool to investigate global changes of RNA-binding protein targets.
Transite, a novel computational method that allows cost-effective, time-effective and comprehensive analysis of the regulatory role of RBPs in various cellular processes by leveraging a wealth of preexisting gene expression data and current knowledge of RBP binding preferences. To gain insights into vastly complex processes including the DNA damage response or the immune response, the preliminary step is to calculate the change of mRNA expression levels after stimulus, i.e., the administration of DNA-damaging agents or an immune stimulus, respectively. Based on these results, Transite provides two approaches to investigate inferred mRNA stability changes due to differences in transcript abundance, Transcript Set Motif Analysis and Spectrum Motif Analysis. The former focuses on significantly upregulated and downregulated sets of transcripts and identifies RBPs whose binding sites are overrepresented among those transcripts, whereas the latter approach examines the distribution of RBP binding sites across the entire spectrum of transcripts, sorted according to their fold change, signal-to-noise ratio or any other meaningful measure of differential expression.
The transite package is part of Bioconductor since release 3.8. To install it on your system, enter:
if (!requireNamespace("BiocManager", quietly = TRUE)) {
install.packages("BiocManager")
}
BiocManager::install("transite")
The above method is recommended for most users, as it is the most recent stable version.
The development version can be installed directly from this repository (most recent, least stable):
if (!requireNamespace("remotes", quietly = TRUE)) {
install.packages("remotes")
}
remotes::install_github("kkrismer/transite")
Alternatively, the development version can be installed using the development branch of Bioconductor:
if (!requireNamespace("BiocManager", quietly = TRUE)) {
install.packages("BiocManager")
}
BiocManager::install(version = "devel")
BiocManager::install("transite")
Note: For most use cases it is not necessary to install the transite package locally, as a substantial part of its functionality is offered as an online service at https://transite.mit.edu.
