The Evolution of Microtubule End-Binding Protein 1 (EB1) and Roles in Regulating Microtubule Behavior
All organisms must transmit genetic information to offspring through cell division, and mitotic spindle participates in the process. Spindle dynamics through depolymerization or polymerization of microtubules generates the driving force required for chromosome movements in mitosis. To date, studies have shown that microtubule arrays control the directions of cell division and diverse microtubul...
متن کاملTobacco mosaic virus movement protein interacts with green fluorescent protein-tagged microtubule end-binding protein 1.
The targeting of the movement protein (MP) of Tobacco mosaic virus to plasmodesmata involves the actin/endoplasmic reticulum network and does not require an intact microtubule cytoskeleton. Nevertheless, the ability of MP to facilitate the cell-to-cell spread of infection is tightly correlated with interactions of the protein with microtubules, indicating that the microtubule system is involved...
متن کاملMicrotubule End Binding: EBs Sense the Guanine Nucleotide State
EB proteins accumulate at the tips of growing microtubules and recruit to them a multitude of factors to regulate microtubule functions. A new study suggests that EBs recognize microtubule ends by distinguishing between different states of the tubulin-bound guanine nucleotide.
متن کاملCharacterization of Microtubule-Binding and Dimerization Activity of Giardia lamblia End-Binding 1 Protein
End-binding 1 (EB1) proteins are evolutionarily conserved components of microtubule (MT) plus-end tracking protein that regulate MT dynamics. Giardia lamblia, with two nuclei and cytoskeletal structures, requires accurate MT distribution for division. In this study, we show that a single EB1 homolog gene of G. lamblia regulates MT dynamics in mitosis. The haemagglutinin-tagged G. lamblia EB1 (G...
متن کاملgamma-tubulin is a minus end-specific microtubule binding protein
The role of microtubules in mediating chromosome segregation during mitosis is well-recognized. In addition, interphase cells depend upon a radial and uniform orientation of microtubules, which are intrinsically asymmetric polymers, for the directional transport of many cytoplasmic components and for the maintenance of the structural integrity of certain organelles. The slow growing minus ends ...
