Active Nuclear Import of Membrane Proteins Revisited

open access: yesCells, 2015
It is poorly understood how membrane proteins destined for the inner nuclear membrane pass the crowded environment of the Nuclear Pore Complex (NPC). For the Saccharomyces cerevisiae proteins Src1/Heh1 and Heh2, a transport mechanism was proposed where ...

A possible mechanism for self coordination of bi-directional traffic across nuclear pores [PDF]

open access: yesPhys. Biol. 5, 036001 (2008), 2008
Nuclear pore complexes are constantly confronted by large fluxes of macromolecules and macromolecular complexes that need to get into and out of the nucleus. Such bi-directional traffic occurring in a narrow channel can easily lead to jamming. How then is passage between the nucleus and cytoplasm maintained under the varying conditions that arise ...

The Structure Inventory of the Nuclear Pore Complex [PDF]

open access: yes, 2018
The nuclear pore complex (NPC) is the principal gateway for molecular exchange between nucleus and cytoplasm across the nuclear envelope. Due to its sheer size of estimated 50-112 MDa and its complex buildup from about 500-1000 individual proteins, it is

Nuclear Envelope Regulation of Oncogenic Processes: Roles in Pancreatic Cancer

open access: yesEpigenomes, 2018
Pancreatic cancer is an aggressive and intractable malignancy with high mortality. This is due in part to a high resistance to chemotherapeutics and radiation treatment conferred by diverse regulatory mechanisms.

Ionic liquids under confinement: From systematic variations of the ion and pore sizes towards an understanding of structure and dynamics in complex porous carbons [PDF]

open access: yesACS Appl. Mater. Inter., 12, 1789 (2020), 2020
We use molecular simulations of an ionic liquid in contact with a range of nanoporous carbons to investigate correlations between ion size, pore size, pore topology and properties of the adsorbed ions. We show that diffusion coefficients increase with the anion size and, surprisingly, with the quantity of adsorbed ions. Both findings are interpreted in

Plant nuclear envelope as a hub connecting genome organization with regulation of gene expression

open access: yesNucleus, 2023
Eukaryotic cells organize their genome within the nucleus with a double-layered membrane structure termed the nuclear envelope (NE) as the physical barrier.

Improving the Hole Picture: Towards a Consensus on the Mechanism of Nuclear Transport [PDF]

open access: yesarXiv, 2023
Nuclear pore complexes (NPCs) mediate the exchange of materials between the nucleoplasm and cytoplasm, playing a key role in the separation of nucleic acids and proteins into their required compartments. The static structure of the NPC is relatively well defined by recent cryo EM and other studies. The functional roles of dynamic components in the pore

Evolution of the nucleus [PDF]

open access: yes, 2014
Under a Creative Commons license.The nucleus represents a major evolutionary transition. As a consequence of separating translation from transcription many new functions arose, which likely contributed to the remarkable success of eukaryotic cells.

FoxO1 signaling in B cell malignancies and its therapeutic targeting

open access: yesFEBS Letters, EarlyView.
FoxO1 has context‐specific tumor suppressor or oncogenic character in myeloid and B cell malignancies. This includes tumor‐promoting properties such as stemness maintenance and DNA damage tolerance in acute leukemias, or regulation of cell proliferation and survival, or migration in mature B cell malignancies.
