Khc is essential for acetylated microtubules and AJ localization.

<p>Stabilized microtubules were stained with Acetub (red), AJs with E-cad (blue), and wild type cells with GFP (green). (A-A″) Distal regions of <i>khc⁸</i> mutant photoreceptors, marked by the absence of GFP (green), display reduction and shrinkage of microtubules (arrow) compared to wild-type cells (double-arrow) and AJs (arrowhead) at the same location. (B-B″) Proximal regions of <i>khc⁸</i> mutant photoreceptors display more severe defects of acetylated microtubules (arrow) and AJs (arrowhead).
