The epitranscriptome includes all post-transcriptional modifications of the RNA
and describes and additional layer of information encoded on RNA. Like the term
epigenome it is not about a change in nucleotide sequences, but the addition of
functional elements through modifications.
With the development of high throughput detection strategies for specific RNA
modifications, such as miCLIP and Pseudo-Seq amongst other, a large number of
modified positions have been identified and were summarized via the RMBase
project ([Xuan et al. 2017, Sun et al. 2015](#Literature)) project.
To make these information avaialble within the Bioconductor universe `EpiTxDb`
was developed, which facilitates the storage of epitranscriptomic information.
More specifically, it can keep track of modification identity, position, the
enzyme for introducing it on the RNA, a specifier which determines the position
on the RNA to be modified and the literature references each modification is
associated with.
# Installation
The current version of the `EpiTxDb` package is available from Bioconductor.
