Advances and challenges in the detection of transcriptome-wide protein-RNA interactions.

Wiley interdisciplinary reviews. RNA · 2018 · 9(1)

RNA binding proteins (RBPs) play key roles in determining cellular behavior by manipulating the processing of target RNAs. Robust methods are required to detect the numerous binding sites of RBPs across the transcriptome. RNA-immunoprecipitation followed by sequencing (RIP-seq) and crosslinking …

Robust, Cost-Effective Profiling of RNA Binding Protein Targets with Single-end Enhanced Crosslinking and Immunoprecipitation (seCLIP).

Methods in molecular biology (Clifton, N.J.) · 2017 · 1648: 177-200

Profiling of RNA binding protein targets in vivo provides critical insights into the mechanistic roles they play in regulating RNA processing. The enhanced crosslinking and immunoprecipitation (eCLIP) methodology provides a framework for robust, reproducible identification of transcriptome-wide protein-RNA interactions, with …

Variation in single-nucleotide sensitivity of eCLIP derived from reverse transcription conditions.

Methods (San Diego, Calif.) · 2017 · 126: 29-37

Crosslinking and immunoprecipitation (CLIP) followed by high-throughput sequencing identifies the binding sites of RNA binding proteins on RNAs. The covalent RNA-amino acid adducts produced by UV irradiation can cause premature reverse transcription termination and deletions (referred to as crosslink-induced mutation …

Protein-RNA Networks Regulated by Normal and ALS-Associated Mutant HNRNPA2B1 in the Nervous System.

Neuron · 2016 · 92(4): 780-795

HnRNPA2B1 encodes an RNA binding protein associated with neurodegeneration. However, its function in the nervous system is unclear. Transcriptome-wide crosslinking and immunoprecipitation in mouse spinal cord discover UAGG motifs enriched within ∼2,500 hnRNP A2/B1 binding sites and an unexpected role …

Pairing beyond the Seed Supports MicroRNA Targeting Specificity.

Molecular cell · 2016 · 64(2): 320-333

To identify endogenous miRNA-target sites, we isolated AGO-bound RNAs from Caenorhabditis elegans by individual-nucleotide resolution crosslinking immunoprecipitation (iCLIP), which fortuitously also produced miRNA-target chimeric reads. Through the analysis of thousands of reproducible chimeras, pairing to the miRNA seed emerged as …

Robust transcriptome-wide discovery of RNA-binding protein binding sites with enhanced CLIP (eCLIP).

Nature methods · 2016 · 13(6): 508-14

As RNA-binding proteins (RBPs) play essential roles in cellular physiology by interacting with target RNA molecules, binding site identification by UV crosslinking and immunoprecipitation (CLIP) of ribonucleoprotein complexes is critical to understanding RBP function. However, current CLIP protocols are technically …

Enhanced CLIP Uncovers IMP Protein-RNA Targets in Human Pluripotent Stem Cells Important for Cell Adhesion and Survival.

Cell reports · 2016 · 15(3): 666-679

Human pluripotent stem cells (hPSCs) require precise control of post-transcriptional RNA networks to maintain proliferation and survival. Using enhanced UV crosslinking and immunoprecipitation (eCLIP), we identify RNA targets of the IMP/IGF2BP family of RNA-binding proteins in hPSCs. At the broad …

LIN28 binds messenger RNAs at GGAGA motifs and regulates splicing factor abundance.

Molecular cell · 2012 · 48(2): 195-206

LIN28 is a conserved RNA-binding protein implicated in pluripotency, reprogramming, and oncogenesis. It was previously shown to act primarily by blocking let-7 microRNA (miRNA) biogenesis, but here we elucidate distinct roles of LIN28 regulation via its direct messenger RNA (mRNA) …
