Researchers reveal a surprising new role for a key protein in cell division

Scientists at the Ruđer Bošković Institute (RBI) in Zagreb, Croatia, have discovered that the protein CENP-E, long believed to act as a motor dragging chromosomes into place during cell division, in fact plays a completely different role in chromosome movement. It stabilizes the first attachments of chromosomes to the cell's internal "tracks," ensuring they line up correctly before being divided.
