deepBase: annotating and discovering small and long RNAs from deep sequencing data

[rnaNGS]

Dear All,

We describe a novel database, deepBase, which we have developed to map, store, retrieve, annotate, integrate and visualize deep sequencing-derived small RNAs, and facilitate transcriptomic research and the discovery of novel ncRNAs.

deepBase is available at: http://deepbase.sysu.edu.cn/

Features of deepBase as follows,
Annotation and identification of diverse small RNAs
we annotated and identified
~380 000 unique ncRNA-associated small RNAs (nasRNAs)
~1.5 million unique promoter-associated small RNAs (pasRNAs)
~4.0 million unique exon-associated small RNAs (easRNAs)
~6 million unique repeat-associated small RNAs (rasRNAs)
Discovering RNA clusters and long ncRNAs
We identified
about 1.2 million RNA clusters that include multiple classes of infrastructural ncRNAs, miRNAs precursor, piRNA precursors, repeat-associated siRNA precursors and evolutionarily conserved phastCons elements.
~2000 microRNA candidates were identified from deep sequencing data using modified miRDeep program.
~1890 snoRNA candidates were predicted from RNA clusters using our snoSeeker program.
Visualization
deepView genome browser, to provide an integrated view of mapped reads, known and predicted ncRNAs, protein-coding genes and RNA clusters and their expression peaks (mapped small RNA density).

This is the first version of deepBase database. We look forward to your feedback.

Thanks!

We are integrating published next-generation small RNA-Seq datasets to our deepBase data. And we hope you contribute your next-generation small RNA-Seq datasets to our deepBase.

Thank you very much!
