Figure 7From: Microtubules regulate disassembly of epithelial apical junctionsKinesin-1 is localized at intact and internalized apical junctions in colonic epithelial cells. In confluent SK-CO-15 (A) and T84 (B) epithelial cell monolayers cultured at high-calcium conditions, kinesin-1 (red color) colocalizes with the TJ protein occludin and the AJ protein β-catenin (arrows). In calcium-depleted cells, kinesin-1 colocalizes with internalized junctional proteins (arrowheads). Bar, 5 μm.Back to article page
