An EB1-Kinesin Complex Is Sufficient to Steer Microtubule Growth In Vitro
Proper microtubule polarity underlies overall neuronal polarity, but mechanisms for maintaining microtubule polarity are not well understood. Previous live imaging in Drosophila dendritic arborization neurons showed that while microtubules are uniformly plus-end out in axons, dendrites possess uniformly minus-end-out microtubules [1]. Thus, maintaining uniform microtubule polarity in dendrites ...
متن کاملMicrotubule organization by kinesin motors and microtubule crosslinking protein MAP65.
Microtubules are rigid, proteinaceous filaments required to organize and rearrange the interior of cells. They organize space by two mechanisms, including acting as the tracks for long-distance cargo transporters, such as kinesin-1, and by forming a network that supports the shape of the cell. The microtubule network is composed of microtubules and a bevy of associated proteins and enzymes that...
متن کاملEchinoderm microtubule-associated protein -like protein 5 in anterior temporal neocortex of patients with intractable epilepsy
Objective(s):EMAP-like Protein 5 (EML5) is a new echinoderm microtubule-associated protein that is expressed in the central nervous system. The aim of this study was to investigate the expression profile of EML5 in the anterior temporal neocortex of patients presenting with intractable epilepsy (IE). Materials and Methods:Western blot assays were performed to determine EML5 expression in 36 su...
متن کاملThe 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 کاملThe kinesin-13 KLP10A motor regulates oocyte spindle length and affects EB1 binding without altering microtubule growth rates
Kinesin-13 motors are unusual in that they do not walk along microtubules, but instead diffuse to the ends, where they remove tubulin dimers, regulating microtubule dynamics. Here we show that Drosophila kinesin-13 klp10A regulates oocyte meiosis I spindle length and is haplo-insufficient - KLP10A, reduced by RNAi or a loss-of-function P element insertion mutant, results in elongated and mispos...
