  • But, says sum folks, if you stop importin 'things you stop the revenoo.

  • Tu LC, Musser SM (2008) Single-molecule measurements of importin alpha/cargo complex dissociation at the nuclear pore.

  • Primary cells express lower levels of nuclear pore complex proteins and the nuclear transport factors, importin B1 and importin 7, which may explain the limiting ERK1/2 import found in primary cells.

  • We show here that regulated nuclear import of p53 also has a critical function. p53 import is mediated by binding to the importin - α3 adapter and is negatively regulated by ubiquitination. p53 harbors several nuclear localization signals (NLS), with the major NLS I located at amino-acids 305-322.

  • We find that direct binding of p53 to importin - α3 depends on the positive charge contributed by lysine residues 319-321 within NLS I.

  • These are: importin (12), CDK/cyclin (22), F-actin (12), PARP1

  • Conversely, stress-induced accumulation of non-ubiquitinated p53 in the cytoplasm promotes interaction with importin - α3 and rapid import.

  • Using glutathione S-transferase pulldown experiments, we provide evidence that heterodimers are required for efficient binding of importin 13 because the monomers alone do not significantly interact.

  • Our results from in vitro nuclear import assays with permeabilized cells and in vivo cotransfection experiments reveal that importin 13 facilitates nuclear import of both histone fold heterodimers.
