| Research Abstract |
The following is the main results of this project. (a) We developed a microRNA finding tool, which combines structural and evolutionary features of microRNAs. We showed that our tool outperforms previous methods with less false positives. (b) We developed an algorithm for computing secondary structural accessibilities of RNA sequences. We were able to detect the evolutionary constraints around the target sites of microRNAs. (c) We developed a tool to calculate the changes of free energies and entropies of RNA secondary structures in response to mutations. We applied our method to mitochondrial tRNAs and showed that the increase of structural fluctuation caused by mutations correlated with disease susceptibility. (d) We developed a tool to predict potential secondary structural contexts for each base of an RNA sequence. We applied our method to binding sites of RNA-binding proteins and detected the structural specificities of the proteins.
