Identification of TRIM32-interacting proteins upon KSHV infection via MALDI-TOF mass spectrometry. Left panel: schematic workflow illustrating the purification of TRIM32 complexes from iSLK cells with and without KSHV infection. Right panel: Coomassie-stained SDS-PAGE gel showing TRIM32-associated protein bands (labeled 1-3) immunoprecipitated from iSLK and KSHV-infected iSLK (iSLK-Bac16) cells. Specific proteins identified by mass spectrometry are indicated adjacent to their corresponding bands. HC, heavy chain; LC, light chain.
