Deficiency in the Tda2–Aim21 complex elicits a similar phenotype as actin-capping protein deficiency. (A) Abp1-GFP was visualized by fluorescence microscopy using live WT cells (AIM21) or aim21Δ cells. (B) Quantification of the Abp1-GFP peak fluorescence intensity at endocytic patches in control (AIM21) and aim21Δ cells. (C) Abp1-GFP was visualized by fluorescence microscopy using live WT cells (TDA2) or tda2Δ cells. (D) Quantification of the Abp1-GFP peak fluorescence intensity at endocytic patches in control (TDA2) and tda2Δ cells. Bars, 1 µm. Error bars indicate means ± SEM. ****, P < 0.0001.
