The Multiple Faces of Disordered Nucleoporins

open access: yesJournal of Molecular Biology, 2016
An evolutionary advantage of intrinsically disordered proteins (IDPs) is their ability to bind a variety of folded proteins-a paradigm that is central to the nucleocytoplasmic transport mechanism, in which nuclear transport receptors mediate the translocation of various cargo through the nuclear pore complex by binding disordered phenylalanine-glycine ...

Compensation for chronic oxidative stress in ALADIN null mice

open access: yesBiology Open, 2018
Mutations in the AAAS gene coding for the nuclear pore complex protein ALADIN lead to the autosomal recessive disorder triple A syndrome. Triple A patients present with a characteristic phenotype including alacrima, achalasia and adrenal insufficiency ...

Targeting self-renewal pathways in myeloid malignancies [PDF]

open access: yes, 2013
A fundamental property of hematopoietic stem cells (HSCs) is the ability to self-renew. This is a complex process involving multiple signal transduction cascades which control the fine balance between self-renewal and differentiation through ...

Triple A patient cells suffering from mitotic defects fail to localize PGRMC1 to mitotic kinetochore fibers

open access: yesCell Division, 2018
Background Membrane-associated progesterone receptors are restricted to the endoplasmic reticulum and are shown to regulate the activity of cytochrome P450 enzymes which are involved in steroidogenesis or drug detoxification.

Membrane-coating lattice scaffolds in the nuclear pore and vesicle coats: Commonalities, differences, challenges [PDF]

open access: yes, 2011
The nuclear pore complex (NPC) regulates all traffic between the cytoplasm and the nucleus. It is a large protein assembly composed of multiple copies of ~30 nucleoporins (nups).

Architecture of the nuclear pore complex coat [PDF]

open access: yes, 2015
The nuclear pore complex (NPC) constitutes the sole gateway for bidirectional nucleocytoplasmic transport. Despite half a century of structural characterization, the architecture of the NPC remains unknown.

Chromatin-prebound Crm1 recruits Nup98-HoxA9 fusion to induce aberrant expression of Hox cluster genes

open access: yeseLife, 2016
The nucleoporin Nup98 is frequently rearranged to form leukemogenic Nup98-fusion proteins with various partners. However, their function remains largely elusive. Here, we show that Nup98-HoxA9, a fusion between Nup98 and the homeobox transcription factor

Nucleoporins and Transcription: New Connections, New Questions

open access: yesPLoS Genetics, 2010
It seems to make perfect sense that RNA, which must be exported from the nucleus to be translated, would be produced near or in association with nuclear pores. Indeed, recent reports proposed that Saccharomyces cerevisiae genes located close to the nuclear pore complex (NPC) tend to be highly transcribed [1],[2] and that, upon activation, some genes ...

Deciphering the 'fuzzy' interaction of FG nucleoporins and transport factors using SANS

open access: yes, 2018
The largely intrinsically disordered phenylalanine-glycine-rich nucleoporins (FG Nups) underline a selectivity mechanism, which enables the rapid translocation of transport factors (TFs) through the nuclear pore complexes (NPCs).

Mitotic Phosphorylation of Nucleoporins: Dismantling NPCs and Beyond [PDF]

open access: yesDevelopmental Cell, 2011
Recently reporting in Cell, Laurell et al. (2011) demonstrate that the hyperphosphorylation of vertebrate Nup98 by distinct mitotic kinases contributes to its release from nuclear pores, drives nuclear envelope permeabilization, and may provide a molecular switch coordinating nuclear envelope breakdown and spindle formation.
