Mitochondrial targeting of Bax requires the 23 amino acids of the TMB region. (A) Anti-GFP Western blots of subcellular fractions from HEK293 cells expressing the indicated EGFP fusion constructs. To test the mitochondrial association of EGFP-23aa-C(Bax), isolated mitochondria were treated with sodium carbonate (pH 12) to remove loosely attached proteins (Att), and the pellet was extracted with detergent (right, Ins). (B) EGFP (green) and anti–mito marker (red) fluorescence analysis of HeLa cells transiently transfected with the indicated EGFP fusion constructs.
