"Under disease conditions, it appears that tau interacts with the nuclear pore and changes its properties," says co-senior study author Bradley T.
In order to move between the nucleus and the cytoplasm, proteins and RNAs must be transported efficiently through nuclear pore complexes (NPCs) that penetrate the nuclear envelope.
After biochemical purification of the cytosolic extract, we isolated a stable complex called the nuclear pore-targeting complex (PTAC) containing the NLS-substrate to target the nuclear pore and found that the complex contains two essential components, a 58-kDa protein called PTAC58 and a 97-kDa protein called PTAC97.
In the early 1990s, investigators realized that specialized proteins, given such names as transportin, importin-alpha, and importin-beta, usher proteins with a nuclear localization signal to and through nuclear pores.
There are also data suggesting that nuclear pore size and nuclear transport rates are being affected at the nucleus.
