Hair-cell localization of proteins involved in apical membrane trafficking. Displayed for each protein (in type I or type II hair cells) are an x-z reslice showing the protein's apical-basal profile, as well as x-y slices at apical, prenuclear, and nuclear levels. A–F, Type I hair cells. G–L, Type II hair cells. A, G: ARF6. B, H: CLTC. C, I: EEA1. D, J: LAMP1. E, K: RAB11. F, L: RAB5. Panel full widths: 18 μm.
