Lipid Droplets Are a Physiological Nucleoporin Reservoir [PDF]
Cells, 2021 Lipid Droplets (LD) are dynamic organelles that originate in the Endoplasmic Reticulum and mostly bud off toward the cytoplasm, where they store neutral lipids for energy and protection purposes.

Role of Nucleoporins and Transport Receptors in Cell Differentiation [PDF]
Frontiers in Physiology, 2020 Bidirectional molecular movements between the nucleus and cytoplasm take place through nuclear pore complexes (NPCs) embedded in the nuclear membrane.

Nucleoporin mediated nuclear positioning and silencing of HMR. [PDF]
PLoS ONE, 2011 The organization of chromatin domains in the nucleus is an important factor in gene regulation. In eukaryotic nuclei, transcriptionally silenced chromatin clusters at the nuclear periphery while transcriptionally poised chromatin resides in the nuclear ...

Proteomic Analysis of Nucleoporin Interacting Proteins [PDF]
Journal of Biological Chemistry, 2001 The Saccharomyces cerevisiae nuclear pore complex is a supramolecular assembly of 30 nucleoporins that cooperatively facilitate nucleocytoplasmic transport. Thirteen nucleoporins that contain FG peptide repeats (FG Nups) are proposed to function as stepping stones in karyopherin-mediated transport pathways.

Multifunctionality of F-rich nucleoporins [PDF]
Biochemical Society Transactions, 2020 Nucleoporins (Nups) represent a range of proteins most known for composing the macromolecular assembly of the nuclear pore complex (NPC). Among them, the family of intrinsically disordered proteins (IDPs) phenylalanine-glycine (FG) rich Nups, form the permeability barrier and coordinate the high-speed nucleocytoplasmic transport in a selective way ...

Autoproteolysis in nucleoporin biogenesis [PDF]
Proceedings of the National Academy of Sciences, 1999 We have molecularly characterized a proteolytic cleavage in conserved nuclear pore complex proteins. This cleavage, previously demonstrated to be essential for the biogenesis of two nuclear pore complex proteins in mammals (Nup98 and Nup96) and yeast (Nup145-N and Nup145-C), occurs between Phe and Ser residues within a highly conserved ...

The Nuclear Life of Nucleoporins [PDF]
Developmental Cell, 2007 Nucleoporins are the constituents of the nuclear pore complex, but they are also known to shuttle to the nuclear interior, the function of which is unclear. In a recent issue of Nature Cell Biology, Wang et al.'s mechanistic studies of leukemogenic fusion proteins that contain nucleoporins suggest that they have a direct role in transcription.

A Nucleoporin at the Meiotic Kinetochore [PDF]
Developmental Cell, 2016 In this issue of Developmental Cell, Hattersley et al. (2016) use the unique biology of meiosis I, in which the cell can exit the division without reforming the nuclear envelope, to uncover an intriguing role of the nucleoporin MEL-28 in mediating chromosome segregation via its interaction with PP1 at the kinetochore.

Depletion of a single nucleoporin, Nup107, prevents the assembly of a subset of nucleoporins into the nuclear pore complex [PDF]
Proceedings of the National Academy of Sciences, 2003 The nuclear pore complex (NPC) is a protein assembly that contains several distinct subcomplexes. The mammalian nucleoporin (Nup)-107 is part of a hetero-oligomeric complex, that also contains Nup160, Nup133, Nup96, and the mammalian homolog of yeast Sec13p. We used transfection of HeLa cells with small interfering RNAs to specifically deplete mRNA for

Nuclear pore complex and stem cell homeostasis
生物医学转化, 2021 As a channel for mediating exchange between the nucleus and cytoplasm, the nuclear pore complex (NPC) is a macromolecular complex composed of about 30 nucleoporins.
