Post-transcriptional gene regulation through the recognition of specific elements in mRNAs is an important determinant of gene expression. The cis elements are recognised by RNA binding proteins (RBPs) and/or small non-coding RNAs, which then orchestrate a range of processes such as mRNA localization, translational control, and degradation. RNA regulation is critical for development and disruptions in regulatory mechanisms can cause disease. While mutations in numerous RBPs have been linked to diseases in humans, the contribution of mutations in RNA elements to disease manifestation is largely unknown. Danio rerio (zebrafish), a fish model is a widely used vertebrate system to study development and disease. Here, we describe how state-of-the-art genomics tools combined with in vivo functional studies in zebrafish have facilitated the discovery of RNA elements, many of which are functionally conserved. We also highlight the potential of zebrafish to model human diseases and for drug discovery.
