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.
