Chromosome-bound RCC1 generates Ran-GTP signals to organize functional spindles for faithful chromosome segregation during mitosis and meiosis. RCC1 is the sole guanine nucleotide exchange factor (GEF) for Ran and is essential for spindle assembly during early, but not late, embryonic divisions. However, how RCC1 organ...

SRP54, a key component of the signal recognition particle, is a highly conserved enzyme both structurally and functionally. The protein plays a vital role in cellular protein translocation by interacting with the translating ribosome and a membrane receptor, thereby aiding protein folding and trafficking. Recent stud...

Bipolar spindle assembly is essential for accurate chromosome segregation. KIFC1, a conserved Ran- regulated minus-end-directed kinesin-14 motor, accumulates in the nucleus during interphase and promotes chromatin-mediated spindle assembly during mitosis and meiosis. In human oocytes, reduced KIFC1 levels destabilize m...
