High-Throughput Identification of Nuclear Envelope Protein Interactions in Schizosaccharomyces pombe Using an Arrayed Membrane Yeast-Two Hybrid Library

G3: Genes, Genomes, Genetics, 2020
The nuclear envelope (NE) contains a specialized set of integral membrane proteins that maintain nuclear shape and integrity and influence chromatin organization and gene expression.

Yeast nuclear envelope proteins cross react with an antibody against mammalian pore complex proteins

Journal of Cell Biology, 1989
We have used a monoclonal antibody raised against rat liver nuclear proteins to study two cross-reactive proteins in the yeast nucleus. In rat liver, this monoclonal antibody, mAb 414, binds to nuclear pore complex proteins, including one of molecular ...

Nuclear Pore-Targeting Complex and Its Role on Nuclear Protein Transport.

Archives of Histology and Cytology, 1996
The process of selective nuclear protein transport is divided into at least two steps: 1) ATP-independent, nuclear localization signal (NLS)-dependent binding to the cytoplasmic face of nuclear pores and 2) ATP-dependent translocation through the nuclear pores.

In Situ Analysis of Spatial Relationships between Proteins of the Nuclear Pore Complex [PDF]

Biophysical Journal, 2002
Macromolecular transport between the nucleus and cytoplasm occurs through the nuclear pore complexes (NPCs). The NPC in the budding yeast Saccharomyces cerevisiae is a 60-MDa structure embedded in the nuclear envelope and composed of ~30 proteins, termed nucleoporins or nups.

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

FEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Super-resolution imaging visualizes the eightfold symmetry of gp210 proteins around the nuclear pore complex and resolves the central channel with nanometer resolution

Journal of Cell Science, 2012
One of the most complex molecular machines of cells is the nuclear pore complex (NPC), which controls all trafficking of molecules in and out of the nucleus.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Phosphoinositides and inositol phosphates as molecular glues

FEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.
