网格蛋白在产生将膜和蛋白质转移到细胞周围的囊泡中具有既定的功能。网格蛋白包被的囊泡的形成在非分裂细胞中连续发生,但在有丝分裂期间当网格蛋白集中在纺锤体时被关闭。在这里,我们表明,网格蛋白稳定有丝分裂纺锤体的纤维,以帮助染色体的集会。网格蛋白通过网格蛋白重链(CHC)的N端结构域直接与纺锤体结合。消耗CHC使用RNA干扰延长有丝分裂;动粒纤维不稳定,导致染色体有缺陷的集会中期板和持续激活的纺锤体检查点。正常的有丝分裂被拯救的网格蛋白triaprotia,但不是N-末端结构域的CHC,表明动粒纤维的稳定是依赖于网格蛋白的独特结构。网格蛋白对正常有丝分裂的重要性可能与理解涉及网格蛋白重链基因融合的人类癌症有关。
Clathrin has an established function in the generation of vesicles that transfer membrane and proteins around the cell. The formation of clathrin-coated vesicles occurs continuously in non-dividing cells, but is shut down during mitosis, when clathrin concentrates at the spindle apparatus. Here we show that clathrin stabilises fibres of the mitotic spindle to aid congression of chromsomes. Clathrin bound the spindle directlyvia the N-terminal domain of clathrin heavy chain (CHC). Depletion of CHC using RNA interference prolonged mitosis; kinetochore fibres were destabilised leading to defective congression of chromosomes to the metaphase plate and persistent activation of the spindle checkpoint. Normal mitosis was rescued by clathrin triskelia but not the N-terminal domain of CHC indicating that stabilisation of kinetochore fibres was dependent on the unique structure of clathrin. The importance of clathrin for normal mitosis may be relevant to understanding human cancers that involve gene fusions of clathrin heavy chain.
