Extended Data Fig. 2: Zip2R(2x) subcellular localization and trafficking determined by confocal microscopy.

a, Schematic of SNAP/CLIP tag system. b, Representative images of Zip2R(2x) with endosomal markers. Scale bar = 10 µm. c-f, Representative images and Zip2R(2x) colocalization analysis of indicated regions of interest (ROI) with (c) cell membrane, (d) Lamp1, (e) Rab11, and (f) Rab5. g, Comparison of Zip2R(2x) and Zip2R(1x) colocalization with indicated subcellular markers (Membrane: N = 14, Lamp1, Rab11, Rab5: N = 4, *p = 0.0224 (membrane), *p = 0.0479 (Lamp1), mean ± SD, two-tailed t-test).
