HyPro-MS analysis of proteins proximal to nuclear noncoding RNAs in HeLa cells


ABSTRACT: The ability of RNAs to form specific contacts with other macromolecules provides an important mechanism for subcellular compartmentalization. We developed a suite of hybridization-proximity (HyPro) labeling technologies for unbiased discovery of proteins (HyPro-MS) and transcripts (HyPro-seq) associated with RNAs of interest in genetically unperturbed cells. To generate the HyPro-MS dataset reported here, fixed and permeabilized HeLa cells were hybridized with digoxigenin-labeled oligonucleotide probes against noncoding RNAs 45S, NEAT1 or PNCTR and proteins co-localizing with these RNAs were biotinylated in situ using a custom-engineered HyPro enzyme containing a digoxigenin-binding domain. Biotinylated proteins were then captured on streptavidin beads and analyzed by LC-MS/MS.
