The Role of Strong Gravity and the Nuclear Equation of State on Neutron-Star Common-Envelope Accretion [PDF]
, 2021 Common-envelope evolution is important in the formation of neutron star binaries within the isolated binary formation channel. As a neutron star inspirals within the envelope of a primary massive star, it accretes and spins up. Because neutron stars are in the strong-gravity regime, they have a substantial relativistic mass deficit, i.e., their ...

Cells, 2023 Regulator of TElomere Length Helicase 1 (RTEL1) is a helicase required for telomere maintenance and genome replication and repair. RTEL1 has been previously shown to participate in the nuclear export of small nuclear RNAs.

Evolution and diversification of the nuclear envelope [PDF]
Nucleus, 2021 Eukaryotic cells arose ~1.5 billion years ago, with the endomembrane system a central feature, facilitating evolution of intracellular compartments. Endomembranes include the nuclear envelope (NE) dividing the cytoplasm and nucleoplasm. The NE possesses universal features: a double lipid bilayer membrane, nuclear pore complexes (NPCs), and continuity ...

TorsinA in the nuclear envelope [PDF]
Proceedings of the National Academy of Sciences, 2004 Early-onset torsion dystonia, a CNS-based movement disorder, is usually associated with a single amino acid deletion (ΔE302/303) in the protein torsinA. TorsinA is an AAA+ ATPase in the endoplasmic reticulum, but what it does is unknown. Here, we use torsinA mutants with defects in ATP hydrolysis (E171Q, ATP-bound) and ATP binding (K108A, ATP-free) to ...

Formation of the postmitotic nuclear envelope from extended ER cisternae precedes nuclear pore assembly [PDF]
, 2011 During mitosis, the nuclear envelope merges with the endoplasmic reticulum (ER), and nuclear pore complexes are disassembled. In a current model for reassembly after mitosis, the nuclear envelope forms by a reshaping of ER tubules.

The effect of diffusive nuclear burning in neutron star envelopes on cooling in accreting systems [PDF]
Monthly Notices of the Royal Astronomical Society, Volume 493,
Issue 4, April 2020, Pages 4936-4944, 2020 Valuable information about the neutron star interior can be obtained by comparing observations of thermal radiation from a cooling neutron star crust with theoretical models. Nuclear burning of lighter elements that diffuse to deeper layers of the envelope can alter the relation between surface and interior temperatures and can change the chemical ...

The subnuclear localization of tRNA ligase in yeast [PDF]
, 1987 Yeast tRNA ligase is an enzyme required for tRNA splicing. A study by indirect immune fluorescence shows that this enzyme is localized in the cell nucleus. At higher resolution, studies using indirect immune electron microscopy show this nuclear location

eLife, 2020 The switch from centrosomal microtubule-organizing centers (MTOCs) to non-centrosomal MTOCs during differentiation is poorly understood. Here, we identify AKAP6 as key component of the nuclear envelope MTOC.

Cold Spring Harbor Perspectives in Biology, 2010 The nuclear envelope (NE) is a highly regulated membrane barrier that separates the nucleus from the cytoplasm in eukaryotic cells. It contains a large number of different proteins that have been implicated in chromatin organization and gene regulation.
