Microtubule Patterns in Dynein-Inhibited Interphase Cells. Interphase microtubule distributions, similar to Figure 4 except that each cell line is also transformed with the dynein motor domain expression plasmid (380 K). AX-2, kif4- and kif11-cells display the distinctive 380 K comet-tail phenotype. However, note the relatively normal, radial distribution of microtubules in the kif8- and kif10- backgrounds. Scale bar = 5 μm.
