Soluble Htt25QP blocks endocytosis in cells lacking Myo5. (a) Images of wild type and myo5Δ cells expressing HTT25QP and HTT25Q and their capacity of endocytic uptake. Scale bar = 5 µm. (b) Quantification of a. Percentage of cells with detectable Htt levels capable of internalizing FM4-64 via the endocytic pathway. Average values from three individual experiments, with more than 150 cells per experiment, are shown. Error bars corresponds to the standard deviation, P = 0.00284. (c) Native PAGE of protein extracts from wild type and myo5Δ cells expressing HTT constructs. Representative picture from three independent experiments is shown. (d) Sucrose density gradient fractionation of protein extracts from wild type and myo5Δ cells expressing HTT25QP. The percentage of Htt25QP protein present in each fraction is quantified in graphs below each Western blot. Values are average from three independent experiments with error bars corresponding to the standard deviation. (Full-length blots are shown in Fig. S12) (e) Fluorescence micrographs of exponentially growing myo5Δ yeast cells expressing indicated HTT constructs. Scale bar = 5 µm.
