In Salmonella-infected cells, the bacterial effector SifA forms a functional complex with the eukaryotic protein SKIP (SifA and kinesin-interacting protein). The lack of either partner has important consequences on the intracellular fate and on the virulence of this pathogen. In addition to SifA, SKIP binds the microtubule-based motor kinesin-1. Yet the(More)
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)
Microtubule dynamics is controlled and amplified in vivo by complex sets of regulators. Among these regulatory proteins, molecular motors from the kinesin superfamily are taking an increasing importance. Here we review how microtubule disassembly or assembly into interphase microtubules, mitotic spindle or cilia may involve kinesins and how protein kinases(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)
