Abstract


MicroRNAs are a group of small, ~21nt long, riboregulators inhibiting gene expression at a posttranscriptional level. Their most distinctive structural feature is the foldback hairpin of their precursor pre-miRNAs. Even though each pre-miRNA deposited in miRBase has its secondary structure already predicted, little is known about the patterns structural conservation among pre-miRNAs. We address this issue by clustering the human pre-miRNA sequences based on pairwise, sequence and secondary structure alignment using <tt>FoldAlign</tt>, followed by global multiple alignment of obtained clusters by WAR. As a result, the common secondary structure was successfully determined for four <tt>FoldAlign</tt> clusters: the RF00027 structural family of the Rfam database and three clusters with previously undescribed consensus structures.
