PITA Target Prediction. Computational tools aim at identifying microRNA targets, usually selecting evolutionarily conserved microRNA binding sites. MicroRNA and mRNA integrated analysis (MMIA) is a web-based tool that integrates miRNA-mRNA expression profile data with three different sequence-based prediction algorithms. Target prediction is generally the first step toward recognition of bona fide microRNA (miRNA)-target interactions in living cells. It first searches for differentially up-regulated miRNAs. The properties used to evaluate each sequence are : microRNA precursor-like structure, sequence similarity with a known microRNA and sequence conservation. 2009;37:3276-3287 59. Nucleic Acids Res 2013; 41(Web Server issue) W169-73. Pearson, W. (2004) Finding protein and nucleotide similarities with FASTA. We developed a tool named TarHunter that features a strict cross-species conservation filter and capability of predicting eTMs. While the false positive rates have been evaluated for some prediction programs, that information is rarely put forward in studies making use of their predictions. Summary: Plant microRNA prediction tools that use small RNA-sequencing data are emerging quickly. These existing tools have at least one of the following problems: (i) high false-positive rate; (ii) long running time; (iii) work only for genomes in their databases; (iv) hard to install or use.
