微管运动驱动蛋白-2及其亚基Kif 3a对于初级纤毛的形成至关重要,初级纤毛是一种与广泛的发育异常有关的细胞器。在纤毛外部,驱动蛋白-2介导的转运与囊泡和N-钙粘蛋白转运有关,但尚不清楚纤毛外Kif 3a是否以及如何影响基本细胞功能,例如迁移或多细胞结构的形成。在这里,我们表明四环素诱导的MDCK细胞中Kif 3a的耗竭减缓了上皮细胞的迁移。在Kif 3a耗尽的细胞的前缘处的微管未能垂直地生长到前缘中,并且微管动力学在Kif 3a耗尽的细胞中被抑制。Kif 3a的缺失延缓了侧膜的特化,并完全阻止了胶原蛋白中三维球体的形成。这些数据揭示了Kif 3a调节细胞周边的微管细胞骨架,并暗示睫状体外Kif 3a在形态发生中具有意想不到的功能。
The microtubular motor Kinesin-2 and its subunit Kif3a are essential for the formation of primary cilia, an organelle implicated in a wide spectrum of developmental abnormalities. Outside cilia, Kinesin-2 mediated transport has been implicated in vesicle and N-cadherin transport, but it is unknown if and how extraciliary Kif3a affects basic cellular functions such as migration or the formation of multicellular structures. Here we show that tetracycline inducible depletion of Kif3a in MDCK cells slows epithelial cell migration. Microtubules at the leading edge of Kif3a depleted cells failed to grow perpendicularly into the leading edge and microtubular dynamics were dampened in Kif3a depleted cells. Loss of Kif3a retarded lateral membrane specification and completely prevented the formation of three-dimensional spheres in collagen. These data uncover that Kif3a regulates the microtubular cytoskeleton in the cell periphery and imply that extra-ciliary Kif3a has an unexpected function in morphogenesis.
