Profiling Translation Rate With Ribo-Eclip

Background

The eukaryotic ribosome is composed of 79 ribosomal protein – large (RPL) and ribosomal protein – small (RPS) subunit proteins that interweave with 4 highly structured RNAs (5S, 5.8S, 18S, and 28S rRNAs) to form the final translation-capable ribonucleoprotein. Thus, quantification of ribosome-associated RNA is highly similar to profiling of RNAs associated with other RNA binding proteins. We recently described the development of enhanced crosslinking and immunoprecipitation (eCLIP), a method to profile RNAs bound by an RNA binding protein of interest that showed thousand-fold improved recovery of protein-bound RNA [Van Nostrand et al 2016].
