Acta Pharmaceutica Sinica B, 2023 Nuclear transporter importin-β1 is emerging as an attractive target by virtue of its prevalence in many cancers. However, the lack of druggable inhibitors restricts its therapeutic proof of concept. In the present work, we optimized a natural importin-β1

NuSAP Safeguards Centriole Integrity to Mediate CEP57‐CEP152 Torus Recruitment for Proper Engagement
Advanced Science, EarlyView.This study reveals a novel role for the microtubule stabilizer NuSAP at centrioles. NuSAP depletion destabilizes the centriole's tubulin structure, causing premature disengagement, PCM defects, and mis‐localization of the CEP57‐CEP63‐CEP152 complex. By reinforcing centriole architecture, NuSAP enables early CEP57 loading and initiates a newly proposed ...

Identification of a Small Molecule Inhibitor of Importin β Mediated Nuclear Import by Confocal On-Bead Screening of Tagged One-Bead One-Compound Libraries [PDF]
, 2010 In eukaryotic cells, proteins and RNAs are transported between the nucleus and the cytoplasm by nuclear import and export receptors. Over the past decade, small molecules that inhibit the nuclear export receptor CRM1 have been identified, most notably ...

Molecular and Cellular Endocrinology, 2016 The thyroid hormone receptor α1 (TRα1) is a nuclear receptor for thyroid hormone that shuttles rapidly between the nucleus and cytoplasm. Our prior studies showed that nuclear import of TRα1 is directed by two nuclear localization signals, one in the N-terminal A/B domain and the other in the hinge domain.

NF-κB Is Transported into the Nucleus by Importin α3 and Importin α4 [PDF]
Journal of Biological Chemistry, 2005 NF-κB transcription factors are retained in the cytoplasm in an inactive form until they are activated and rapidly imported into the nucleus. We identified importin α3 and importin α4 as the main importin α isoforms mediating TNF-α-stimulated NF-κB p50/p65 heterodimer translocation into the nucleus.

Chicken Pulmonary MicroRNAs Targeting the PB2 (Segment 1) of Avian Influenza Virus
Animal Research and One Health, EarlyView.The PB2 segment of H5N1 is essential for replication and host adaptation. We screened 200 miRNAs and identified five (gga‐miR‐17‐3p, gga‐miR‐29a‐5p, gga‐miR‐1718, gga‐miR‐16c‐5p, and gga‐miR‐1744‐5p) using thermodynamic stability of heteroduplex, seed sequence complementarity, conservation, and accessibility, offering insights into host antiviral ...

Conformational Selection in the Recognition of the Snurportin Importin β Binding Domain by Importin β [PDF]
Biochemistry, 2010 The structural flexibility of beta-karyopherins is critical to mediate the interaction with transport substrates, nucleoporins, and the GTPase Ran. In this paper, we provide structural evidence that the molecular recognition of the transport adaptor snurportin by importin beta follows the population selection mechanism. We have captured two drastically
