Please read the posting guide. miR166 family generally comprises multiple miR166 members in plants, which might exhibit functional redundancy and specificity. MiRBase is the primary online repository for all microRNA sequences and annotation. Griffiths-Jones S, Grocock RJ, van Dongen S, Bateman A, Enright AJ. MicroRNAs (miRNAs) are small non-coding RNAs that are involved in post-transcriptional regulation of gene expression. ac. -g specify the appropriate genome version for the version of miRBase that you are using. miRBase Tracker. In bioinformatics, miRBase is a biological database that acts as an archive of microRNA sequences and annotations. PubMed ID: 17604727 A mammalian microRNA expression atlas based on small RNA library sequencing "Landgraf P, Rusu M, Sheridan R, Sewer A, Iovino N, Aravin A, Pfeffer S, Rice A, Kamphorst AO, Landthaler M, Lin C, Socci ND, Hermida L, Fulci V, Chiaretti S, Foa R, Schliwka J, Fuchs U, Novosel A, Muller RU, Schermer B, Bissels U, Inman J, Phan Q,. Hi, I am wondering how to generate "human_mirna_SNP_pseudo_miRBase. 0) contains 5071 miRNA loci from 58 species, expressing 5922 distinct mature miRNA sequences: a growth of over 2000 sequences in the past 2 years.
