Correct dosage of X chromosome transcription is controlled by a nuclear pore component
Cell Reports, 2021 Summary: Dosage compensation in Drosophila melanogaster involves a 2-fold transcriptional upregulation of the male X chromosome, which relies on the X-chromosome-binding males-specific lethal (MSL) complex.

The Nuclear Pore Complex: Birth, Life, and Death of a Cellular Behemoth
Cells, 2022 Nuclear pore complexes (NPCs) are the only transport channels that cross the nuclear envelope. Constructed from ~500–1000 nucleoporin proteins each, they are among the largest macromolecular assemblies in eukaryotic cells.

Prion formation by a yeast GLFG nucleoporin [PDF]
Prion, 2012 The self-assembly of proteins into higher order structures is both central to normal biology and a dominant force in disease. Certain glutamine/asparagine (Q/N)-rich proteins in the budding yeast Saccharomyces cerevisiae assemble into self-replicating amyloid-like protein polymers, or prions, that act as genetic elements in an entirely protein-based ...

Nucleoporin Nup62 maintains centrosome homeostasis [PDF]
Cell Cycle, 2013 Centrosomes are comprised of 2 orthogonally arranged centrioles surrounded by the pericentriolar material (PCM), which serves as the main microtubule organizing center of the animal cell. More importantly, centrosomes also control spindle polarity and orientation during mitosis.

Cell Reports, 2015 CRM1 is the major nuclear export receptor. During translocation through the nuclear pore, transport complexes transiently interact with phenylalanine-glycine (FG) repeats of multiple nucleoporins. On the cytoplasmic side of the nuclear pore, CRM1 tightly

Functional interactions between nucleoporins and chromatin [PDF]
Current Opinion in Cell Biology, 2011 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

Communicative & Integrative Biology, 2018 The nuclear pore complex (NPC) is the sole gateway for molecular transport between the nucleus and the cytoplasm in eukaryotes. The NPC is composed of approximately 30 different kinds of protein components called nucleoporins. The functional structure of

Nucleoporin Nup98: a gatekeeper in the eukaryotic kingdoms [PDF]
Genes to Cells, 2010 The nucleoporin Nup98 is an essential component of the nuclear pore complex. This peripheral nucleoporin with its Gly‐Leu‐Phe‐Gly (GLFG) repeat domain contributes to nuclear‐cytoplasmic trafficking, including mRNA export. In addition, accumulating studies indicate that Nup98 plays roles in several important biological events such as gene expression ...
