Abstract

To determine the molecular and functional interactions between RNA-binding proteins (RBPs) and their targets RNAs, is of fundamental importance to understand the dynamic organization of the nervous system in health and disease. Nevertheless, this task has remained elusive due to the lack of specific protocols and experimental systems that would allow the combination of biochemical analysis with in vivo functional genetics. In this manuscript, we describe a trustworthy and detailed methodology to establish the molecular organization and intracellular function of RBPs/RNA multimeric complexes in a cell type-defined manner by using the powerful GAL4/UAS system for gene expression in Drosophila melanogaster.
