  Introduction

RegRNA 2.0 is an integrated web server for identifying functional RNA motifs in an input RNA sequence. RegRNA 2.0 extends our previvous work, RegRNA which is a widely used regulatory RNA motifs identification tool (times cited: 47#) by incoporating more analytical methods and updated data sources. Through our integrated user-friendly interface, user can conveniently use these analytical approaches and observe results with good graphical visualization. Serveral kinds of functional RNA motifs and sites can be identified by RegRNA 2.0:
  ▪ Splicing sites (donor site, acceptor site)
  ▪ Splicing regulatory motifs(ESE, ESS, ISE, ISS elements)
  ▪ Polyadenylation sites
  ▪ Transcriptional motifs (rho-independent terminator, TRANSFAC)
  ▪ Translational motifs (ribosome binding sites)
  ▪ UTR motifs (UTRsite patterns)
  ▪ mRNA degradation elements (AU-rich elements)
  ▪ RNA editing sites (C-to-U editing sites)
  ▪ Riboswitches (RiboSW)
  ▪ RNA cis-regulatory elements (Rfam, ERPIN)
  ▪ Similar funcitonal RNA sequences (fRNAdb)
  ▪ RNA-RNA interaction regions (miRNA, ncRNA)
  ▪ User defined Motif (RNAMotif)
  ▪ Miscellaneous information (open reading frame, GC-ratio, RNA accessibility and etc.)

   Improvements of RegRNA 2.0

As compared with RegRNA, RegRNA 2.0 integrates more data and is capable of identifying more types of functional RNA motifs (as shown in Table below). In addition, RegRNA 2.0 provides further analysis and related information for predictive results, and presents results with good graphical visualization.
