Robust single-cell discovery of RNA targets of RNA binding proteins and ribosomes [RNA-seq]

ABSTRACT: RNA binding proteins (RBPs) are critical regulators of gene expression and RNA processing that are required for gene function. Yet, the dynamics of RBP regulation in single cells is unknown. To address this gap in understanding, we developed STAMP (Surveying Targets by APOBEC Mediated Profiling), which efficiently detects RBP RNA interactions. STAMP does not rely on UV crosslinking or immunoprecipitation and, when coupled with single cell capture, can identify RBP and cell type specific RNA protein interactions for multiple RBPs and cell types in single pooled experiments. Pairing STAMP with long read sequencing also yields RBP target sites for full length isoforms. Finally, conducting STAMP using small ribosomal subunits (RiboSTAMP) allows analysis of transcriptome wide ribosome association in single cells. STAMP enables the study of RBP RNA interactomes and translational landscapes with unprecedented cellular resolution.

Robust single-cell discovery of RNA targets of RNA binding proteins and ribosomes [STAMP_pacbio]

Project description:RNA binding proteins (RBPs) are critical regulators of gene expression and RNA processing that are required for gene function. Yet, the dynamics of RBP regulation in single cells is unknown. To address this gap in understanding, we developed STAMP (Surveying Targets by APOBEC Mediated Profiling), which efficiently detects RBP-RNA interactions. STAMP does not rely on UV-crosslinking or immunoprecipitation and, when coupled with single-cell capture, can identify RBP- and cell type-specific RNA-protein interactions for multiple RBPs and cell types in single, pooled experiments. Pairing STAMP with long-read sequencing yields RBP target sites in an isoform-specific manner. Finally, Ribo-STAMP leverages small ribosomal subunits to measure transcriptome-wide ribosome association in single cells. STAMP enables the study of RBP-RNA interactomes and translational landscapes with unprecedented cellular resolution.

Expanded repertoire of RNA-editing-based detection for RNA binding protein interactions (2)

Project description:RNA binding proteins (RBPs) are key regulators of RNA processing and cellular function. Technologies to discover RNA targets of RBPs such as TRIBE (targets of RNA binding proteins identified by editing) and STAMP (surveying targets by APOBEC1 mediated profiling) utilize fusions of RNA base-editors (rBEs) to RBPs to circumvent the limitations of immunoprecipitation (CLIP)-based methods that require enzymatic digestion and large amounts of input material. To expand the collection of rBEs suitable for editing-based RBP-RNA interactome studies, we developed experimental and computational assays to systematically evaluate the editing activities of over thirty A-to-I and C-to-U rBEs in human cells. We identify rBEs that outperform Drosophila ADAR (TRIBE) and mammalian APOBEC1 (STAMP) in the characterization of the binding patterns of sequence-specific and broad-binding RBPs and recommend rBEs that pair effectively in dual-RBP-based applications. We demonstrate that the optimal choice of single or multiple rBEs to fuse to a given or pair of RBPs depends on the editing biases of the rBEs and the binding preferences of the RBPs. Our framework ENGRAVe (Editing nucleotides with general RNA-base-editor variants) reframes the use of and expands the choice of rBEs for the next generation of RBP-RNA target discoveries.
