Nuclear Import and Export Signals of Human Cohesins SA1/STAG1 and SA2/STAG2 Expressed in Saccharomyces cerevisiae [PDF]
Background: Human SA/STAG proteins, homologues of the yeast Irr1/Scc3 cohesin, are the least studied constituents of the sister chromatid cohesion complex crucial for proper chromosome segregation.

Karyopherin α 3 and Karyopherin α 4 Proteins Mediate the Nuclear Import of Methyl-CpG Binding Protein 2 [PDF]
Methyl-CpG binding protein 2 (MeCP2) is a nuclear protein with important roles in regulating chromatin structure and gene expression, and mutations in MECP2 cause Rett syndrome (RTT). Within the MeCP2 protein sequence, the nuclear localization signal (NLS) is reported to reside between amino acids 255-271, and certain RTT-causing mutations overlap with

The adapter importin‐α provides flexible control of nuclear import at the expense of efficiency
Although there exists a large family of nuclear transport receptors (Karyopherins), the majority of known import cargoes use an adapter protein, Importin‐α (Impα), which links the cargo to a karyopherin, Importin‐β (Impβ). The reason for the existence of

Nuclear import of yeast Gcn4p requires karyopherins Srp1p and Kap95p
The yeast transcription factor Gcn4p contains two stretches of amino acid residues, NLS1 and NLS2, which are independently able to relocate the cytoplasmic protein chorismate mutase into the nucleus. Only NLS2 is conserved among fungi.

Importins and Exportins Regulating Allergic Immune Responses
Nucleocytoplasmic shuttling of macromolecules is a well-controlled process involving importins and exportins. These karyopherins recognize and bind to receptor-mediated intracellular signals through specific signal sequences that are present on cargo ...

Drosophila TIM binds importin α1, and acts as an adapter to transport PER to the nucleus. [PDF]
Regulated nuclear entry of clock proteins is a conserved feature of eukaryotic circadian clocks and serves to separate the phase of mRNA activation from mRNA repression in the molecular feedback loop.

Cognitive and Neuroimaging Divergence Between Juvenile and Adult FUS Amyotrophic Lateral Sclerosis
ABSTRACT Objective Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by progressive motor neuron degeneration. Fused in sarcoma (FUS)‐associated juvenile ALS (jALS) represents a distinct and aggressive subgroup with rapid deterioration and poor prognosis.

Evolutionary and Transcriptional Analysis of Karyopherin β Superfamily Proteins [PDF]
In eukaryotes, karyopherin beta superfamily proteins mediate nucleocytoplasmic transport of macromolecules. We investigated the evolutionary and transcriptional patterns of these proteins using bioinformatics approaches. No obvious homologs were found in prokaryotes, but an extensive set of beta-karyopherin proteins was found in yeast.

Dissecting in vivo steady-state dynamics of karyopherin-dependent nuclear transport [PDF]
Karyopherin-dependent molecular transport through the nuclear pore complex is maintained by constant recycling pathways of karyopherins coupled with the Ran-dependent cargo catch-and-release mechanism.

Survival, bacterial clearance and thrombocytopenia are improved in polymicrobial sepsis by targeting nuclear transport shuttles. [PDF]
The rising tide of sepsis, a leading cause of death in the US and globally, is not adequately controlled by current antimicrobial therapies and supportive measures, thereby requiring new adjunctive treatments.
