text: Nucleocytoplasmic transport occurs exclusively through nuclear pore complexes
(NPCs) embedded in pores formed by inner and outer nuclear membrane fusion. The
mechanism for de novo pore and NPC biogenesis remains unclear. Reticulons (RTNs)
and Yop1/DP1 are conserved membrane protein families required to form and maintain
the tubular endoplasmic reticulum (ER) and the postmitotic nuclear envelope. In
this study, we report that members of the RTN and Yop1/DP1 families are required
for nuclear pore formation. Analysis of Saccharomyces cerevisiae prp20-G282S and
nup133Δ NPC assembly mutants revealed perturbations in Rtn1–green fluorescent
protein (GFP) and Yop1-GFP ER distribution and colocalization to NPC clusters.
Combined deletion of RTN1 and YOP1 resulted in NPC clustering, nuclear import
defects, and synthetic lethality with the additional absence of Pom34, Pom152,
and Nup84 subcomplex members. We tested for a direct role in NPC biogenesis using
Xenopus laevis in vitro assays and found that anti-Rtn4a antibodies specifically
inhibited de novo nuclear pore formation. We hypothesize that these ER membrane–bending
proteins mediate early NPC assembly steps.

text: The nuclear envelope (NE) provides a selective barrier between the nuclear
interior and the cytoplasm and constitutes a central component of intracellular
architecture. During mitosis in metazoa, the NE breaks down leading to the complete
mixing of the nuclear content with the cytosol. Interestingly, many NE components
actively participate in mitotic progression. After chromosome segregation, the
NE is reassembled around decondensing chromatin and the nuclear compartment is
reestablished in the daughter cells. Here, we summarize recent progress in deciphering
the molecular mechanisms underlying NE dynamics during cell division.

text: Nuclear pore complexes are large aqueous channels that penetrate the nuclear
envelope, thereby connecting the nuclear interior with the cytoplasm. Until recently,
these macromolecular complexes were viewed as static structures, the only function
of which was to control the molecular trafficking between the two compartments.
It has now become evident that this simplistic scenario is inaccurate and that
nuclear pore complexes are highly dynamic multiprotein assemblies involved in
diverse cellular processes ranging from the organization of the cytoskeleton to
gene expression. In this review, we discuss the most recent developments in the
nuclear-pore-complex field, focusing on the assembly, disassembly, maintenance
and function of this macromolecular structure.

text: During mitosis in metazoans, segregated chromosomes become enclosed by the
nuclear envelope (NE), a double membrane that is continuous with the endoplasmic
reticulum (ER). Recent in vitro data suggest that NE formation occurs by chromatin-mediated
reorganization of the tubular ER; however, the basic principles of such a membrane-reshaping
process remain uncharacterized. Here, we present a quantitative analysis of nuclear
membrane assembly in mammalian cells using time-lapse microscopy. From the initial
recruitment of ER tubules to chromatin, the formation of a membrane-enclosed,
transport-competent nucleus occurs within ∼12 min. Overexpression of the ER tubule-forming
proteins reticulon 3, reticulon 4, and DP1 inhibits NE formation and nuclear expansion,
whereas their knockdown accelerates nuclear assembly. This suggests that the transition
from membrane tubules to sheets is rate-limiting for nuclear assembly. Our results
provide evidence that ER-shaping proteins are directly involved in the reconstruction
of the nuclear compartment and that morphological restructuring of the ER is the
principal mechanism of NE formation in vivo.

text: The nuclear envelope is a double-layered membrane that encloses the nuclear
genome and transcriptional machinery. In dividing cells of metazoa, the nucleus
completely disassembles during mitosis, creating the need to re-establish the
nuclear compartment at the end of each cell division. Given the crucial role of
the nuclear envelope in gene regulation and cellular organization, it is not surprising
that its biogenesis and organization have become active research areas. We will
review recent insights into nuclear membrane dynamics during the cell cycle.

text: The nuclear envelope (NE), a double membrane enclosing the nucleus of eukaryotic
cells, controls the flow of information between the nucleoplasm and the cytoplasm
and provides a scaffold for the organization of chromatin and the cytoskeleton.
In dividing metazoan cells, the NE breaks down at the onset of mitosis and then
reforms around segregated chromosomes to generate the daughter nuclei. Recent
data from intact cells and cell-free nuclear assembly systems suggest that the
endoplasmic reticulum (ER) is the source of membrane for NE assembly. At the end
of mitosis, ER membrane tubules are targeted to chromatin via tubule ends and
reorganized into flat nuclear membrane sheets by specific DNA-binding membrane
proteins. In contrast to previous models, which proposed vesicle fusion to be
the principal mechanism of NE formation, these new studies suggest that the nuclear
membrane forms by the chromatin-mediated reshaping of the ER.

text: The formation of the nuclear envelope (NE) around chromatin is a major membrane-remodelling
event that occurs during cell division of metazoa. It is unclear whether the nuclear
membrane reforms by the fusion of NE fragments or if it re-emerges from an intact
tubular network of the endoplasmic reticulum (ER). Here, we show that NE formation
and expansion requires a tubular ER network and occurs efficiently in the presence
of the membrane fusion inhibitor GTPγS. Chromatin recruitment of membranes, which
is initiated by tubule-end binding, followed by the formation, expansion and sealing
of flat membrane sheets, is mediated by DNA-binding proteins residing in the ER.
Thus, chromatin plays an active role in reshaping of the ER during NE formation.

text: Over the last years it has become evident that the nuclear envelope (NE) is
more than a passive membrane barrier that separates the nucleus from the cytoplasm.
The NE not only controls the trafficking of macromolecules between the nucleoplasm
and the cytosol, but also provides anchoring sites for chromosomes and cytoskeleton
to the nuclear periphery. Targeting of chromatin to the NE might actually be part
of gene expression regulation in eukaryotes. Mutations in certain NE proteins
are associated with a diversity of human diseases, including muscular dystrophy,
neuropathy, lipodistrophy, torsion dystonia and the premature aging condition
progeria. Despite the importance of the NE for cell division and differentiation,
relatively little is known about its biogenesis and its role in human diseases.
It is our goal to provide a comprehensive view of the NE and to discuss possible
implications of NE-associated changes for gene expression, chromatin organization
and signal transduction.

text: The nuclear envelope (NE) is a highly specialized membrane that delineates
the eukaryotic cell nucleus. It is composed of the inner and outer nuclear membranes,
nuclear pore complexes (NPCs) and, in metazoa, the lamina. The NE not only regulates
the trafficking of macromolecules between nucleoplasm and cytosol but also provides
anchoring sites for chromatin and the cytoskeleton. Through these interactions,
the NE helps position the nucleus within the cell and chromosomes within the nucleus,
thereby regulating the expression of certain genes. The NE is not static, rather
it is continuously remodeled during cell division. The most dramatic example of
NE reorganization occurs during mitosis in metazoa when the NE undergoes a complete
cycle of disassembly and reformation. Despite the importance of the NE for eukaryotic
cell life, relatively little is known about its biogenesis or many of its functions.
We thus are far from understanding the molecular etiology of a diverse group of
NE-associated diseases.

text: The small GTPase Ran is a key regulator of nucleocytoplasmic transport during
interphase. The asymmetric distribution of the GTP-bound form of Ran across the
nuclear envelope — that is, large quantities in the nucleus compared with small
quantities in the cytoplasm — determines the directionality of many nuclear transport
processes. Recent findings that Ran also functions in spindle formation and nuclear
envelope assembly during mitosis suggest that Ran has a general role in chromatin-centred
processes. Ran functions in these events as a signal for chromosome position.

text: ICln is an ion channel identified by expression cloning using a cDNA library
from Madin-Darby canine kidney cells. In all organisms tested so far, only one
transcript for the ICln protein could be identified. Here we show that two splice
variants of the ICln ion channel can be found in Caenorhabditis elegans. Moreover,
we show that these two splice variants of the ICln channel protein, which we termed
IClnN1 and IClnN2, can be functionally reconstituted and tested in an artificial
lipid bilayer. In these experiments, the IClnN1-induced currents showed no voltage-dependent
inactivation, whereas the IClnN2-induced currents fully inactivated at positive
potentials. The molecular entity responsible for the voltage-dependent inactivation
of IClnN2 is a cluster of positively charged amino acids encoded by exon 2a, which
is absent in IClnN1. Our experiments suggest a mechanism of channel inactivation
that is similar to the “ball and chain” model proposed for the Shaker potassium
channel,i.e. a cluster of positively charged amino acids hinders ion permeation
through the channel by a molecular and voltage-dependent interaction at the inner
vestibulum of the pore. This hypothesis is supported by the finding that synthetic
peptides with the same amino acid sequence as the positive cluster can transform
the IClnN1-induced current to the current observed after reconstitution of IClnN2.
Furthermore, we show that the nematode ICln gene is embedded in an operon harboring
two additional genes, which we termed Nx and Ny. Co-reconstitution of Nx and IClnN2
and functional analysis of the related currents revealed a functional interaction
between the two proteins, as evidenced by the fact that the IClnN2-induced current
in the presence of Nx was no longer voltage-sensitive. The experiments described
indicate that the genome organization in nematodes allows an effective approach
for the identification of functional partner proteins of ion channels.

text: Although nuclear envelope (NE) assembly is known to require the GTPase Ran,
the membrane fusion machinery involved is uncharacterized. NE assembly involves
formation of a reticular network on chromatin, fusion of this network into a closed
NE and subsequent expansion. Here we show that p97, an AAA-ATPase previously implicated
in fusion of Golgi and transitional endoplasmic reticulum (ER) membranes together
with the adaptor p47, has two discrete functions in NE assembly. Formation of
a closed NE requires the p97–Ufd1–Npl4 complex, not previously implicated in membrane
fusion. Subsequent NE growth involves a p97–p47 complex. This study provides the
first insights into the molecular mechanisms and specificity of fusion events
involved in NE formation.

text: Nuclear import of the two uracil-rich small nuclear ribonucleoprotein (U snRNP)
components U1A and U2B′′ is mediated by unusually long and complex nuclear localization
signals (NLSs). Here we investigate nuclear import of U1A and U2B′′ in vitro and
demonstrate that it occurs by an active, saturable process. Several lines of evidence
suggest that import of the two proteins occurs by an import mechanism different
to those characterized previously. No cross competition is seen with a variety
of previously studied NLSs. In contrast to import mediated by members of the importin-β
family of nucleocytoplasmic transport receptors, U1A/U2B′′ import is not inhibited
by either nonhydrolyzable guanosine triphosphate (GTP) analogues or by a mutant
of the GTPase Ran that is incapable of GTP hydrolysis. Adenosine triphosphate
is capable of supporting U1A and U2B′′ import, whereas neither nonhydrolyzable
adenosine triphosphate analogues nor GTP can do so. U1A and U2B′′ import in vitro
does not require the addition of soluble cytosolic proteins, but a factor or factors
required for U1A and U2B′′ import remains tightly associated with the nuclear
fraction of conventionally permeabilized cells. This activity can be solubilized
in the presence of elevated MgCl2. These data suggest that U1A and U2B′′ import
into the nucleus occurs by a hitherto uncharacterized mechanism.

text: Nuclear formation in Xenopus egg extracts requires cytosol and is inhibited
by GTPγS, indicating a requirement for GTPase activity. Nuclear envelope (NE)
vesicle fusion is extensively inhibited by GTPγS and two mutant forms of the Ran
GTPase, Q69L and T24N. Depletion of either Ran or RCC1, the exchange factor for
Ran, from the assembly reaction also inhibits this step of NE formation. Ran depletion
can be complemented by the addition of Ran loaded with either GTP or GDP but not
with GTPγS. RCC1 depletion is only complemented by RCC1 itself or by RanGTP. Thus,
generation of RanGTP by RCC1 and GTP hydrolysis by Ran are both required for the
extensive membrane fusion events that lead to NE formation.

text: We prove lower bounds on the complexity of maintaining fully dynamic k -edge
or k -vertex connectivity in plane graphs and in (k-1) -vertex connected graphs.
We show an amortized lower bound of Ω (log n / {k (log log n} + log b)) per edge
insertion, deletion, or query operation in the cell probe model, where b is the
word size of the machine and n is the number of vertices in G . We also show an
amortized lower bound of Ω (log n /(log log n + log b)) per operation for fully
dynamic planarity testing in embedded graphs. These are the first lower bounds
for fully dynamic connectivity problems.

text: Arrangements of curves in the plane are of fundamental significance in many
problems of computational and combinatorial geometry (e.g. motion planning, algebraic
cell decomposition, etc.). In this paper we study various topological and combinatorial
properties of such arrangements under some mild assumptions on the shape of the
curves, and develop basic tools for the construction, manipulation, and analysis
of these arrangements. Our main results include a generalization of the zone theorem
of [EOS], [CGL] to arrangements of curves (in which we show that the combinatorial
complexity of the zone of a curve is nearly linear in the number of curves), and
an application of (some weaker variant of) that theorem to obtain a nearly quadratic
incremental algorithm for the construction of such arrangements.
