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

Nucleoporins facilitate ORC loading onto chromatin
Cell Reports, 2022 SUMMARYThe origin recognition complex (ORC) binds throughout the genome to initiate DNA replication. In metazoans, it is still unclear how ORC is targeted to specific loci to facilitate helicase loading and replication initiation. Here, we performed immunoprecipitations coupled with mass spectrometry for ORC2 in Drosophila embryos.

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.

Nuclear distributions of NUP62 and NUP214 suggest architectural diversity and spatial patterning among nuclear pore complexes. [PDF]
PLoS ONE, 2012 The shape of nuclei in many adherent cultured cells approximates an oblate ellipsoid, with contralateral flattened surfaces facing the culture plate or the medium.

Pvr expression regulators in equilibrium signal control and maintenance of Drosophila blood progenitors. [PDF]
, 2014 Blood progenitors within the lymph gland, a larval organ that supports hematopoiesis in Drosophila melanogaster, are maintained by integrating signals emanating from niche-like cells and those from differentiating blood cells.

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.

Viruses Challenge Selectivity Barrier of Nuclear Pores
Viruses, 2013 Exchange between the nucleus and the cytoplasm occurs through nuclear pore complexes (NPCs) embedded in the double membrane of the nuclear envelope. NPC permeability barrier restricts the entry of inert molecules larger than 5 nm in diameter but allows ...

MicroRNA-222 regulates muscle alternative splicing through Rbm24 during differentiation of skeletal muscle cells [PDF]
, 2016 A number of microRNAs have been shown to regulate skeletal muscle development and differentiation. MicroRNA-222 is downregulated during myogenic differentiation and its overexpression leads to alteration of muscle differentiation process and specialized ...
