Protocol to isolate RBP-mRNA complexes using RNA CLIP and examine target mRNAs-

RNA-binding proteins (RBPs) regulate diverse functions by interacting with target transcripts. Here we present a protocol to isolate RBP-mRNA complexes using RNA-CLIP and examine target mRNAs in association with ribosomal popu-lations. We describe steps to identify specific RBPs and RNA targets reflecting a variety of developmental, physiological, and pathological states. This protocol enables RNP complex isolation from tissue sources (liver and small intestine) or populations of primary cells (hepatocytes), but not at a single-cell level. For complete details on the use and execution of this protocol, please refer to Blanc et al. (2014)1 and Blanc et al. (2021).2
