Abstract:
The interaction between RNAs and RNA-binding proteins (RBPs) is fundamental for gene expression and regulation of cellular homeostasis. The growing interest in understanding protein-RNA complexes and their use in developing biotechnological solutions has highlighted the need for computational resources to enable detailed structural analysis of these interactions. Despite the availability of structural databases, there is still a significant gap in specialized databases that integrate, in a curated, systematic, and up-to-date manner, structural information on these complexes. Here, we propose RNApedia, a specialized, curated database of protein-RNA complexes accessible via an interactive and user-friendly web interface. The database brings together systematic analyses of 56,133 protein-RNA pairs. It integrates structural descriptors, including accessible and hidden surface areas, atomic contacts and interaction types, RNA classification, protein domains, RNA modifications, and, when available, affinity data. RNApedia is a scalable and integrative platform for exploring protein-RNA interactions, serving as a promising resource for structural bioinformatics and data-driven approaches, including applications in artificial intelligence. All data are freely available for download at: https://bioinfo.dcc.ufmg.br/rnapedia.

RNA Structure
The basic structure of RNA consists of a five-carbon sugar and one of four nitrogenous bases. Although most RNA is single-stranded, it can form complex secondary and tertiary structures. Such structures play essential roles in the regulation of transcription and translation.
