The transferred DNA (T-DNA) is escorted, by two bacterial proteins, as a single-stranded DNA-protein complex (a T-complex), which mediate its transport to the host nucleus. The large size and mass of this DNA-protein complex raise questions as to the molecular machinery and mechanism by which

The localization of these processes in two different compartments of the cell implies that macromolecules must be exchanged very rapidly and efficiendy between the nucleus and the cytoplasm in order to ensure proper regulation of signaling and metabolism of a living

Subsequent to translocation through the pore via a series of importin-mediated docking steps at multiple sites within it, release into the nucleus is effected by th

In particular, it was assumed that general mRNA export was mediated by one or more transport receptors of the importin-β family and that the RanGTP/GDP gradient was required to impart directionality to the process.

Regardless, the mechanism is the same: NLS-containing proteins, either provided by
