Nucleocytoplasmic Trafficking Perturbation Induced by Picornaviruses
Picornaviruses are positive-stranded RNA viruses. Even though replication and translation of their genome take place in the cytoplasm, these viruses evolved different strategies to disturb nucleocytoplasmic trafficking of host proteins and RNA. The major

Mutations in the Lotus japonicus nucleoporin genes, NUP85, NUP133 and NENA (SEH1), lead to defects in plant-microbe symbiotic signaling. The homologous proteins in yeast and vertebrates are part of the conserved NUP84/NUP107-160 sub-complex, which is an ...

Dictyostelium cells undergo a semi-closed mitosis, during which the nuclear envelope (NE) persists; however, free diffusion between the cytoplasm and the nucleus takes place.

Depletion of a single nucleoporin, Nup107, prevents the assembly of a subset of nucleoporins into the nuclear pore complex [PDF]
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

Viral Subversion of the Nuclear Pore Complex
The nuclear pore complex (NPC) acts as a selective barrier between the nucleus and the cytoplasm and is responsible for mediating communication by regulating the transport of RNA and proteins. Numerous viral pathogens have evolved different mechanisms to

Non-classical functions of nuclear pore proteins in ciliopathy
Nucleoporins (NUPs) constitute integral nuclear pore protein (NPC) elements. Although traditional NUP functions have been extensively researched, evidence of additional vital non-NPC roles, referred to herein as non-classical NUP functions, is also ...

The Role of Protein Disorder in Nuclear Transport and in Its Subversion by Viruses
The transport of host proteins into and out of the nucleus is key to host function. However, nuclear transport is restricted by nuclear pores that perforate the nuclear envelope.

Non-transport roles of nuclear import receptors: In need of the right balance
Nuclear import receptors ensure the recognition and transport of proteins across the nuclear envelope into the nucleus. In addition, as diverse processes as mitosis, post-translational modifications at mitotic exit, ciliogenesis, and phase separation ...

Functional interactions between nucleoporins and chromatin [PDF]
As the gatekeepers of the eukaryotic cell nucleus, nuclear pore complexes (NPCs) mediate all molecular trafficking between the nucleoplasm and the cytoplasm. In recent years, transport-independent functions of NPC components, nucleoporins, have been identified including roles in chromatin organization and gene regulation. Here, we summarize our current
