| Research Abstract |
Phosphorylation of plant microtubules was investigated with respects to tubulin phosphorylation and protein phosphatases. I found that the Arabidopsis Propyzamide-Hypersensitive 1 protein of the mitogen-activated protein kinase phosphatase family also possesses a kinase domain of atypical protein kinases. The kinase activity is suppressed by the intra-molecular phosphatase activity, but when this suppression is removed, the activated kinase rapidly phosphorylates tubulin and depolymerizes cortical microtubules.
