Three CLIP-based protocols—irCLIP-RNP, irCLIPv2, and Re-CLIP—map RNA-dependent associated proteins and binding regions with improved precision versus conventional CLIP, resolving adjacent interactions.
- Why it matters: Existing transcriptome-wide CLIP approaches struggle to distinguish closely spaced RNA–protein contacts, limiting mechanistic understanding of ribonucleoprotein assembly and post-transcriptional regulation in living cells.
- What they did: The workflows use an infrared biotinylated DNA adapter with UV cross-linking, partial RNase digestion, protein immunoprecipitation, and 3' DNA adapter ligation, then apply mass spectrometry, RNA-seq, or a second IP plus sequencing.
- The result: Custom analyses identify enriched RDAPs or significant binding sites, and the full pipeline from cell harvesting through data analysis can be completed in 7-10 d, enabling studies of regulatory networks across cell states and stimuli.
