Abstract
The preprophase band (PPB) of microtubules (MTs) marks the site of the future division plane irrespective of the orientation of the equatorial plane. Because the PPB MTs disappear during prometaphase, some positional information is thought to remain in the cortical cytoplasm after the disappearance of the PPB MTs. Cytoskeletal proteins are known to be excluded from the PPB site during mitosis. These depleted zones of cytoskeletal proteins are potential candidates for a "negative memory" system. However, how these depleted zones of the cytoskeletal proteins are produced remains unknown. In a recent paper, we have quantified the distribution of clathrin-coated pits and vesicles as well as of secretory structures during PPB formation using a combination of high-pressure freezing and electron tomography techniques. Our results demonstrated that the rate of endocytosis is enhanced in PPB regions. We postulate that the removal of membrane proteins by endocytosis plays a role in the creation of PPB "memory" structures.
摘要
微管（MT）的前期带（PPB）标记了未来分裂平面的位置，而与赤道面的方向无关。由于PPB微管在有丝分裂前期消失，所以有人认为在PPB微管消失后，一些位置信息会保留在皮质细胞质中。已知细胞骨架蛋白在有丝分裂期间被排除在PPB位点之外。这些细胞骨架蛋白的耗尽区是“负记忆”系统的潜在候选者。然而，这些细胞骨架蛋白的耗尽区是如何产生的仍然未知。在最近的一篇论文中，我们结合高压冷冻和电子断层扫描技术，对PPB形成过程中网格蛋白包被小窝和囊泡以及分泌结构的分布进行了量化。我们的结果表明，PPB区域的内吞作用速率增强。我们推测，通过内吞作用去除膜蛋白在PPB“记忆”结构的形成中起作用。
