Abstract microRNA is a small RNA molecule that controls gene expression at the
posttranscriptional level. It can regulate the expression of one or more target mRNAs. Owing
to the biological importance of the miRNA target relationship, several tools have been
developed to provide information about the experimentally validated and predicted miRNA
targets as well as their interactions. In this chapter, we have reviewed the databases as well
as predictive tools that have been developed for miRNA targets. It focuses on the importance …
