Welcome to microPIR database
microPIR (microRNA-Promoter Interaction Resource) is an integrated database for microRNA target sites within human promoter sequences. In animals, microRNAs are generally understood to regulate gene expression through binding to target sequences within 3'UTRs of mRNAs, therefore the computational prediction of target sites is regularly limited to such regions. Recent experimental studies have suggested an alternative microRNA role in modulating gene expression through promoter recognition in human cells. To facilitate the comprehensive exploration of miRNA-promoter interactions, this database aims to collect genome-wide predicted microRNA target sites located within promoter regions of human genome, incorporated with considerable resources of associated genomic information and functional annotation. The predicted target data are managed in a way that enables the interactive and flexible exploration of putative binding sites that are most suitable with users' hypotheses, especially in the global view along with associated genomic features which can be visualized in a genome browser view format.
