Origin of the nucleus and Ran-dependent transport to safeguard ribosome biogenesis in a chimeric cell

Gáspár Jékely Biology Direct 2008, 3:31 (24 July 2008)

Nuclear compartmentalization in eukaryotes evolved via the coevolution of Ran and karyopherin dependent transport, nuclear membranes and nuclear pore complexes in order to reduce the number of chimeric ribosomes which formed after the acquisition of the protomitochondrium.
