CRISPR-assisted RNA-protein interaction detection (CARPID) combined with quantitative mass spectrometry was used to identify proteins interacting with the long non-coding RNA (lncRNA) Taurine Up-regulated 1 (TUG1) in HEK293T cells under physiological conditions and after Camptothecin (CPT) treatment.

This project utilized CRISPR-assisted RNA-protein interaction detection (CARPID) combined with mass spectrometry to identify proteins interacting with the long non-coding RNA (lncRNA) TUG1 in HEK293T cells. TUG1 preferentially interacts with known R-loop-associated proteins, particularly under Camptothecin (CPT) treatment. Additionally, we identified interacting proteins for the lncRNAs MALAT1 to validate the binding specificity of TUG1.
