Method |
To determine whether budding yeast Kip3p is a microtubule
depolymerase, the full-length His-tagged protein was expressed in
insect cells, purified to homogeneity and its activity measured in
sedimentation assays. |
Comments |
Because their speed was faster
than the microtubule growth rate of 1.4±0.4µm/min (primary source), Kip3p
spots always caught up with the ends of growing microtubules, leading
to bright plus-end labelling (Fig. 4). See p.960 right column top paragraph for "typical microtubule growth
rates of ~1µm/min" |
