Internalized NHE3 colocalizes with SNX27 in EEA-1– and Rab5-containing vesicles near the plasma membrane. (A) Biochemical internalization assay of HA-NHE3 in SK-CO15 cells. Representative examples of fluorescence localization pattern of endogenous SNX27 (red) and internalized NHE3 (green). The inset shows a magnified image of the boxed area. (B, C). Cellular localization of endogenous SNX27 (green) and EEA1 (red) in SK-CO15 and HEK293 cells, respectively. (D) HEK293 cells were transfected with early endosome marker GFP-rab5a or (E) recycling marker GFP-rab4a or (F) GFP-rab11a. The colocalization of endogenous SNX27 (green) and endosomal marker (red) was determined with anti-SNX27 antibody and anti-GFP antibodies. Scale bar, 10 μm. Representative images from six or seven independent experiments with similar results.
