Welcome to Vir-Mir database, a database containing predicted viral miRNA candidate hairpins. This database is constructed and maintained by the Transcriptome Discovery Lab(TDL), Institute of BioMedical Science, Academia Sinica, Taipei, Taiwan.
We have previously identified human intronic microRNA as well as zebrafish microRNA. The microRNA hairpin discovery pipeline was also applied to discover viral encoded microRNAs. All viral genomes were obtain from NCBI. The classification of virus is based on the taxonomy table of NCBI (Jun, 2006). Totally, the genomes of 2266 viruses were analyzed. Users may query the putative miRNA hairpins of a specific viral species by the hierarchical menu or by search function using the GenBank Identifier or RefSeq accession number(e.g. 30844336 or NC_003663 for Cowpox virus). In addition, users can also search for the putative target genes of a particular viral miRNA hairpins by a RNAhybrid service link. The 3'-UTR regions of human, mouse, rat, zebrafish, arabidopsis and rice genes are available for search. RNAhybrid program is kindly provide by Dr. Rehmsmeier (Original paper:"Fast and effective prediction of microRNA/target duplexes.").
