Welcome to circBase
Thousands of circular RNAs (circRNAs) have recently been shown to be expressed in eukaryotic cells [Salzman et al. 2012, Jeck et al. 2013, Memczak et al. 2013, Salzman et al. 2013]. Here you can explore public circRNA datasets and download the custom python scripts needed to discover circRNAs in your own (ribominus) RNA-seq data.
New:
- Sequence-based search
- Search the database by identifier, gene description, genomic position, or their lists.
- Retrieve dataset slices by defining a set of conditions (table browser).
- Export tables in a variety of formats.
- Export FASTA files containing genomic sequence. Please refer to documentation for further info.
- HTML tables from circBase 0.1 are available here.
- Custom python scripts used to report circRNAs can be downloaded here.
