Early Steps of Hepatitis B Life Cycle: From Capsid Nuclear Import to cccDNA Formation

Viruses, 2021
Hepatitis B virus (HBV) remains a major public health concern, with more than 250 million chronically infected people who are at high risk of developing liver diseases, including cirrhosis and hepatocellular carcinoma.

Kap-Centric control of nuclear pores based on promiscuous binding to FG nucleoporins [PDF]

, 2014
Nuclear pore complexes (NPCs) are remarkable molecular machines that perforate the nuclear envelope (NE) in eukaryotic cells and mediate the rapid bidirectional traffic of hundreds of proteins, ribonucleoproteins, and metabolites across the nuclear ...

Establishment and inheritance of epigenetic transcriptional memory

Frontiers in Molecular Biosciences, 2022
For certain inducible genes, the rate and molecular mechanism of transcriptional activation depends on the prior experiences of the cell. This phenomenon, called epigenetic transcriptional memory, accelerates reactivation and requires both changes in ...

Pore surface exploration by NMR [PDF]

, 2003
A carefully chosen set of experimental techniques applied to porous media characterization provides results that can be much greater than the sum of the individual parts.

Role of SAGA in the asymmetric segregation of DNA circles during yeast ageing

eLife, 2014
In eukaryotes, intra-chromosomal recombination generates DNA circles, but little is known about how cells react to them. In yeast, partitioning of such circles to the mother cell at mitosis ensures their loss from the population but promotes replicative ...

Dynamic rearrangement of nucleoporins during fungal "open" mitosis [PDF]

, 2008
Mitosis in animals starts with the disassembly of the nuclear pore complexes and the breakdown of the nuclear envelope. In contrast to many fungi, the corn smut fungus Ustilago maydis also removes the nuclear envelope.

Nup133 Is Required for Proper Nuclear Pore Basket Assembly and Dynamics in Embryonic Stem Cells

Cell Reports, 2018
Summary: Nup133 belongs to the Y-complex, a key component of the nuclear pore complex (NPC) scaffold. Studies on a null mutation in mice previously revealed that Nup133 is essential for embryonic development but not for mouse embryonic stem cell (mESC ...

OCTAGONAL NUCLEAR PORES [PDF]

The Journal of Cell Biology, 1967
Negative staining of isolated nuclear envelopes by phosphotungstate shows that the nuclear pores are octagonal rather than circular. Pores of the same shape and approximately the same width, 663 ± 5 A, were demonstrated in the newt, Triturus, the frog, Rana, and the starfish, Henricia.

Baculovirus Nuclear Import: Open, Nuclear Pore Complex (NPC) Sesame

Viruses, 2013
Baculoviruses are one of the largest viruses that replicate in the nucleus of their host cells. During infection, the rod-shape, 250-nm long nucleocapsid delivers its genome into the nucleus.
