Updated FTP location. MM1.S cells stably expressing AGIA-AirID-CRBN-WT were treated with DMSO, 1 µM pomalidomide, or 0.1 µM ARV-825 in the presence of 5 µM biotin and 5 µM MG132 for 6 h in three biological replicates. After tryptic digestion, biotinylated peptides were enriched with Tamavidin 2-REV and analyzed by LC-MS/MS.
