We constructs a global-scale landscape of RNA-RNA interactions involving various classes of ncRNAs (lncRNAs, snoRNAs, tRNAs, snRNAs, pseudogenes and miRNAs) and mRNAs by re-analyzing high-throughput RNA interactome data from SPLASH, MARIO, PARIS and LIGR-seq methods. We using stringent parameters to filter all RNA-RNA interactions and identified ~0.1 million lncRNA-RNA interactions, ~1.2 million mRNA-RNA interactions and ~0.4 million small ncRNAs(sncRNAs)-RNA interactions, such as snoRNA-target, snRNA-target and miRNA-target interactions.
We also provides minimum free energy (MFE), smith-waterman alignment score, pairwise alignments and experimental number to allow user to filter these RNA-RNA interactions. A huge number of novel RNA-RNA interactions highlight the complexity of RNA interactomes and serve as important resources for elucidating the regulatory network of various ncRNAs and understanding the biological functions of RNA organization.
