Fig. 5. Cubn is not localized to the apical cell surface in Amn-deficient KPT.
Immunohistochemical analyses of serial paraffin sections (A,D,G) from an adult
chimeric kidney with high contribution of Amn-/- cells.
Two sets of serial high magnification views are shown in B,E,H and C,F,I.
(A-C) Cubn, (D-F) Amn and (G-I) megalin antibody staining of wild-type KPT
(blue asterisks; WT) and Amn-deficient KPT (red asterisks;
mut). A chimeric tubule (green asterisks; ch), which
contains both wild-type and Amn-/- cells, is designated as
well as a distal tubule (yellow asterisks; DT). Of significance, Cubn
does not localize to the apical surface in Amn-deficient KPT but is
observed in the cytoplasm (B,C).
