Involved in a wide range of cellular processes such as signal transduction, microtubules are highly dynamic polymers that accumulate various post-translational modifications including polyglutamylation, polyglycylation, carboxyterminal cleavage and acetylation, the functions of which just begin to be uncovered. The molecular chaperone Hsp90, which is(More)
In the kinesin family, all the molecular motors that have been implicated in the regulation of microtubule dynamics have been shown to stimulate microtubule depolymerization. Here, we report that kinesin-1 (also known as conventional kinesin or KIF5B) stimulates microtubule elongation and rescues. We show that microtubule-associated kinesin-1 carries the(More)
To better understand the relationship between the subcellular compartmentalization of endothelial nitric oxide synthase (eNOS) and its function in endothelial cells, we addressed the roles of the microtubule network and of its dynamics in organizing Golgi-bound eNOS. We found that part of Golgi-bound eNOS localizes to the trans-Golgi network and/or to(More)
