GSK3β phosphorylation modulates CLASP–microtubule association and lamella microtubule attachment
Polarity of the microtubule (MT) cytoskeleton is essential for many cell functions. Cytoplasmic linker-associated proteins (CLASPs) are MT-associated proteins thought to organize intracellular MTs and display a unique spatiotemporal regulation. In migrating epithelial cells, CLASPs track MT plus ends in the cell body but bind along MTs in the lamella. In this study, we demonstrate that glycogen...
متن کاملA CLASP-modulated cell edge barrier mechanism drives cell-wide cortical microtubule organization in Arabidopsis
It is well known that the parallel order of microtubules in the plant cell cortex defines the direction of cell expansion, yet it remains unclear how microtubule orientation is controlled, especially on a cell-wide basis. Here we show through 4D imaging and computational modelling that plant cell polyhedral geometry provides spatial input that determines array orientation and heterogeneity. Mic...
متن کاملThe cortical microtubule array: from dynamics to organization.
Cortical microtubules (CMTs) are essential for normal plant morphogenesis because they affect the axes of cell elongation and predict the placement of cell division planes. The function of the CMTs is intimately linked to their organizational state, which is subject to spatial and temporal modifications by developmental and environmental cues. CMT assembly dynamics govern when, where, and how m...
