Based on analyses of conventional RNA binding motifs, there are well over 550 RNA binding proteins produced in living cells. Thus a detailed understanding of the mechanisms of post-transcriptional regulation requires an understanding of how these trans-acting factors act in both local and combinatorial fashions. The goal of this chapter is to provide a roadmap for approaching the identification of RNA–protein interactions and how to decipher fundamental aspects of their roles in the regulation of gene expression. Many of the techniques outlined below are applicable to the study of RNA–RNA interactions as well. Collectively they should provide a rational approach to gain mechanistic insights into a variety of post-transcriptional processes.
