RIMap-RISC is a web-accessible database for transcriptome-wide modeling of human microRNA (miRNA) targeting. It computes plausible transcript-miRNA interactions and records their position, duplex secondary structure, free energy, site classification, dissociation constant, target accessibility, and evolutionary conservation. RIMap-RISC supports transcript-wide queries and allows users to explore and export interaction data through an interactive interface or RESTful API programmatic access. Unlike existing tools, RIMap-RISC integrates duplex-structure prediction within a biophysical framework modeling the bipartite architecture of RISC, accommodating a bridge between seed and supplementary pairing. A novel, unambiguous, miRNA-centric nomenclature for interaction types is also introduced.
Keywords: Computational RNA biology; Dissociation constants; MicroRNA targeting; Non-canonical interactions; Post-transcriptional regulation; RNA accessibility; RNA duplex structure; RNA regulons; Transcriptome-wide analysis.
