Nuclear Transport: Run by Ran? [PDF]
The American Journal of Human Genetics, 1998 A distinguishing feature of eukaryotic cells is the compartmentalization of their DNA within the nucleus. The sequestration of the genetic material away from the translational machinery and cytosolic proteins has at least two obvious but important implications: First, there must be a mechanism whereby the separate identities of the nucleus and cytosol ...

Nuclear Import of Hepatitis B Virus Capsids and Genome
Viruses, 2017 Hepatitis B virus (HBV) is an enveloped pararetrovirus with a DNA genome, which is found in an up to 36 nm-measuring capsid. Replication of the genome occurs via an RNA intermediate, which is synthesized in the nucleus.

Viral Appropriation: Laying Claim to Host Nuclear Transport Machinery
Cells, 2019 Protein nuclear transport is an integral process to many cellular pathways and often plays a critical role during viral infection. To overcome the barrier presented by the nuclear membrane and gain access to the nucleus, virally encoded proteins have ...

Active Nuclear Import of Membrane Proteins Revisited
Cells, 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 ...

Cell biological mechanisms of activity-dependent synapse to nucleus translocation of CRTC1 in neurons. [PDF]
, 2015 Previous studies have revealed a critical role for CREB-regulated transcriptional coactivator (CRTC1) in regulating neuronal gene expression during learning and memory. CRTC1 localizes to synapses but undergoes activity-dependent nuclear translocation to

An agent-based model for mRNA export through the nuclear pore complex. [PDF]
, 2014 mRNA export from the nucleus is an essential step in the expression of every protein- coding gene in eukaryotes, but many aspects of this process remain poorly understood.

Nuclear transport and transcriptional regulation [PDF]
FEBS Letters, 1999 Studies over the past 10 years have provided major insights into the molecular mechanisms responsible for active transport of macromolecules in and out of the nucleus. Nucleocytoplasmic transport pathways correspond to active and signal‐mediated processes that involve substrates, adaptors and receptors.

Microscopic Transport Theory of Nuclear Processes [PDF]
, 2009 We formulate a microscopic theory of the decay of a compound nucleus through fission which generalizes earlier microscopic approaches of fission dynamics performed in the framework of the adiabatic hypothesis.

Frontiers in Immunology, 2023 The Th17+ arrangement is critical for orchestrating both innate and acquired immune responses. In this context, the serum and glucocorticoid regulated kinase 1 (SGK1) exerts a key role in the governance of IL-23R-dependent Th17+ maturation, through the ...

Structure-based nuclear import mechanism of histones H3 and H4 mediated by Kap123
eLife, 2017 Kap123, a major karyopherin protein of budding yeast, recognizes the nuclear localization signals (NLSs) of cytoplasmic histones H3 and H4 and translocates them into the nucleus during DNA replication.
