Abstract
Trypanosomatids rely primarily on posttranscriptional mechanisms for the control of gene expression, with regulation of RNA processing, localization, degradation, and translation by RNA-binding proteins (RBPs). To determine the mechanisms by which RBPs control gene expression in trypanosomatids, transcriptome-wide identification of mRNA targets and mapping of the RNA-binding site is required. Here we present our most current RIP-Seq (RNA immunoprecipitation followed by high-throughput sequencing) protocol that we generally apply to elucidate RNA/protein interactions in Trypanosoma brucei. The technique provides valuable information about the workings of messenger ribonucleoprotein (mRNP) networks and trypanosome gene expression mechanisms.
