A novel function for the Caenorhabditis elegans torsin OOC-5 in nucleoporin localization and nuclear import. [PDF]
Torsin proteins are AAA+ ATPases that localize to the endoplasmic reticular/nuclear envelope (ER/NE) lumen. A mutation that markedly impairs torsinA function causes the CNS disorder DYT1 dystonia. Abnormalities of NE membranes have been linked to torsinA

The Structure of the Nuclear Pore Complex (An Update).
The nuclear pore complex (NPC) serves as the sole bidirectional gateway of macromolecules in and out of the nucleus. Owing to its size and complexity (∼1,000 protein subunits, ∼110 MDa in humans), the NPC has remained one of the foremost challenges for ...

Summary: Nuclear pore complexes are pathways for nuclear-cytoplasmic communication that participate in chromatin organization. Here, we present a protocol to image and quantify the number of nuclear pore complexes in cells.

New Family Members of FG Repeat Proteins and Their Unexplored Roles During Phase Separation
The condensation and compartmentalization of biomacromolecules in the cell are driven by the process of phase separation. The main effectors of phase separation are intrinsically disordered proteins, which include proteins with a phenylalanine-glycine ...

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.

The nuclear pore‐targeting complex binds to nuclear pores after association with a karyophile [PDF]
We recently showed that a karyophilic protein forms a stable complex, termed nuclear pore‐targeting complex (PTAC), with cytoplasmic components prior to nuclear porebinding. In this study, we cloned a cDNA encoding a 97 kDa of PTAC (PTAC97). Recombinant PTAC97 completely reconstitutes the nuclear binding‐step in conjunction with a 58 kDa component of ...

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

TFEB/Mitf links impaired nuclear import to autophagolysosomal dysfunction in C9-ALS
Disrupted nucleocytoplasmic transport (NCT) has been implicated in neurodegenerative disease pathogenesis; however, the mechanisms by which disrupted NCT causes neurodegeneration remain unclear.

Establishment and inheritance of epigenetic transcriptional memory
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 ...

In yeast, collapsed forks shift to the nuclear periphery to associate with two distinct perinuclear anchorage sites such as the nuclear pore complex. Here, the authors reveal the mechanisms engaged at nuclear pore complex facilitating fork integrity and ...
