In the project “ULK1 regulated phosphatases” by Zehan Hu, Devanarayanan Siva Sankar, Björn Stork and Jörn Dengjel two sets of bottom-up MS-based chemical proteomics experiments were performed in which phosphatase complexes were enriched based on their activity using microcystin-LR coupled sepharose beads. (1) Three biological replicates of MEFs (triple labeling) were performed comparing phosphatase activity (36 raw files labeled "2018"). ULK1 MEFs were compared DKO MEFs, both in rapamycin conditions. Empty beads were used as negative control (Ctrl). Following experiments were performed: (2) Three biological replicates of A549 cells (triple labeling) were performed comparing phosphatase activity (30 raw files labeled "A549"). A549 cells in fed conditions (DMEM) were compared to rapamycin treated cells (Rapa). Empty beads were used as negative control (Ctrl).
