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 populations. 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)
