Structural and biochemical characterization of the Importin-β·Ran·GTP·RanBD1 complex
Here we present the crystal structure of Importin-β(1–462)·Ran·GTP·RanBD1ΔN as solved by molecular replacement. HPLC dissociation measurements on this complex show, that the N-terminus of RanBD may be involved in the release of the hydrolysis- and ...

Subcellular Knockout of Importin β1 Perturbs Axonal Retrograde Signaling
SummarySubcellular localization of mRNA enables compartmentalized regulation within large cells. Neurons are the longest known cells; however, so far, evidence is lacking for an essential role of endogenous mRNA localization in axons.

Importin beta regulates mitosis via distinct molecular mechanisms
Importin beta is the major vector for protein import in interphase nuclei and acts as an effector of the GTPase RAN. After nuclear envelope breakdown, when nuclear transport ceases, Importin beta acts in control of mitosis. Importin beta is overexpressed
VERRICO, ANNALISA
core
The 'classical' nuclear protein import pathway depends on importin alpha and importin beta. Importin alpha binds nuclear localization signal (NLS)-bearing proteins and functions as an adapter to access the importin beta dependent import pathway.

Model for importin 7- and Nup358-assisted import of hTERT.
Cytoplasmic hTERT (TERT) interacts with Nup358, the major component of the cytoplasmic filaments of the NPC (blue rods). Upon binding of importin 7, hTERT is translocated across the NPC.

Importin alpha associates with membranes and participates in nuclear envelope assembly in vitro [PDF]
Importin alpha is well known as an adaptor that functions with Importin beta in the nuclear import of proteins containing specific nuclear localization signals (NLSs). We show here that either an excess or a lack of Importin alpha blocks nuclear envelope

Distinct energy requirement for nuclear import and export of importin β in living cells
Importin β can shuttle between the nucleus and cytoplasm through the nuclear pore complex (NPC). This study deals with the issue of how the energy is utilized during the NPC passage of importin β.

Differential recognition of canonical NF-κB dimers by Importin α3
Nuclear translocation of the p50/p65 heterodimer is essential for NF-κB signaling. In unstimulated cells, p50/p65 is retained by the inhibitor IκBα in the cytoplasm that masks the p65-nuclear localization sequence (NLS).
