Regulation of Op18 during Spindle Assembly in Xenopus Egg Extracts [PDF]

open access: yes, 2001
Oncoprotein 18 (Op18) is a microtubule-destabilizing protein that is negatively regulated by phosphorylation. To evaluate the role of the three Op18 phosphorylation sites in Xenopus (Ser 16, 25, and 39), we added wild-type Op18, a nonphosphorylatable ...

Importin alpha can migrate into the nucleus in an importin beta- and Ran-independent manner [PDF]

open access: yesThe EMBO Journal, 2002
A classical nuclear localization signal (NLS)-containing protein is transported into the nucleus via the formation of a NLS-substrate/importin alpha/beta complex. In this study, we found that importin alpha migrated into the nucleus without the addition of importin beta, Ran or any other soluble factors in an in vitro transport assay. A mutant importin

Arabidopsis AUGMIN8 Contains Two Independent Microtubule Association Domains

open access: yesCytoskeleton, EarlyView.
ABSTRACT Plant cells create a plasma membrane‐associated network of microtubules that are nucleated by γ‐tubulin ring complexes primarily through microtubule‐dependent microtubule nucleation (MDMN). This dynamic array organizes into specific patterns in response to developmental and environmental cues to influence primary cell wall construction.

Formation of the postmitotic nuclear envelope from extended ER cisternae precedes nuclear pore assembly [PDF]

open access: yes, 2011
During mitosis, the nuclear envelope merges with the endoplasmic reticulum (ER), and nuclear pore complexes are disassembled. In a current model for reassembly after mitosis, the nuclear envelope forms by a reshaping of ER tubules.

Ruthenium Complexes in Protein Science: Heading a New Generation of Therapeutic and Analytical Tools

open access: yesAngewandte Chemie, Volume 138, Issue 4, 22 January 2026.
This review presents the latest advances in the development of ruthenium complexes within the field of protein science, highlighting their potential applications in biomedical and bioanalytical fields. Abstract Ruthenium complexes are distinguished by their versatile coordination chemistry, redox behaviors and photochemical properties. In recent years,

Nuclear import factors importin α and importin β undergo mutually induced conformational changes upon association [PDF]

open access: yesFEBS Letters, 2000
A heterodimer of importin α and importin β accomplishes the nuclear import of proteins carrying classical nuclear localization signals (NLS). The interaction between the two import factors is mediated by the IBB domain of importin α and involves an extended recognition surface as shown by X‐ray crystallography.

Nuclear Alpha‐Synuclein: Mechanisms and Implications for Synucleinopathies

open access: yesMovement Disorders, EarlyView.
Abstract Alpha‐synuclein (aSyn), historically studied for its synaptic functions and central role in Lewy body pathology, is emerging as a protein with significant nuclear activities relevant to Parkinson's disease (PD) and related synucleinopathies. Recent advances reveal that aSyn dynamically localizes to neuronal nuclei in both health and disease ...

Comparative proteomic profiling reveals molecular characteristics associated with oogenesis and oocyte maturation during ovarian development of Bactrocera dorsalis (Hendel) [PDF]

open access: yes, 2017
Time-dependent expression of proteins in ovary is important to understand oogenesis in insects. Here, we profiled the proteomes of developing ovaries from Bactrocera dorsalis (Hendel) to obtain information about ovarian development with particular ...

Vascular miR‐181b controls tissue factor‐dependent thrombogenicity and inflammation in type 2 diabetes [PDF]

open access: yes, 2020
BACKGROUND: Diabetes mellitus is characterized by chronic vascular inflammation leading to pathological expression of the thrombogenic full length (fl) tissue factor (TF) and its isoform alternatively-spliced (as) TF. Blood-borne TF promotes factor (

Tick Importin-α Is Implicated in the Interactome and Regulome of the Cofactor Subolesin

open access: yesPathogens, 2021
Ticks and tick-borne diseases (TBDs) represent a burden for human and animal health worldwide. Currently, vaccines constitute the safest and most effective approach to control ticks and TBDs.
