(B) P-Taf12 was followed by anti-FLAG IB of protein extracts from sty1Η cells (left panel) or ssp2Η cells (right panel), grown in rich conditions (R) or starved for 45 minutes (S). An anti-tubulin IB is shown as a control for loading. The star (*) symbols label an unspecific band detected by the anti-FLAG antibody in S. pombe. Shown are IBs that are representative of 2 independent experiments.
