Updated FTP location. IMR32 cells stably expressing AGIA-AirID-CRBN or AGIA-TurboID-CRBN were treated with DMSO or 10 µM pomalidomide in the presence of 10 µM biotin and 5 µM MG132 for 2 h in three biological replicates. After tryptic digestion, biotinylated peptides were enriched with Tamavidin 2-REV and analyzed by LC-MS/MS analysis.
