M(R)apping RNA-Protein Interactions

Methods Mol Biol. 2021:2254:259-272. doi: 10.1007/978-1-0716-1158-6_16.

Abstract

The systematic investigation of RNA-protein interactions is a key step towards a better understanding of the functions of RNA molecules.We developed an easy-to-use method to isolate and identify RNAs and proteins bound to long non-coding RNAs (lncRNAs ) in their native configuration. Similar to other methodologies, we utilize biotinylated antisense oligonucleotides (ASOs) to purify the lncRNA of interest and its associated proteins from different cellular compartments.

Keywords: Mass spectrometry; Proteins; RAP; Subcellular fractions; lncRNAs.
