Kinetochore dynein is sufficient to biorient chromosomes and remodel the outer kinetochore

Nature Communications
Multiple microtubule-directed activities concentrate on mitotic chromosomes to ensure their faithful segregation. These include couplers and dynamics regulators localized at the kinetochore, the microtubule interface built on centromeric chromatin, as ...

Lateral and End-On Kinetochore Attachments Are Coordinated to Achieve Bi-orientation in Drosophila Oocytes.

PLoS Genetics, 2015
In oocytes, where centrosomes are absent, the chromosomes direct the assembly of a bipolar spindle. Interactions between chromosomes and microtubules are essential for both spindle formation and chromosome segregation, but the nature and function of ...

In Vitro Kinetochore Assembly [PDF]

, 2016
The kinetochore is the primary site of interaction between chromosomes and microtubules of the mitotic spindle during chromosome segregation. Kinetochores are composed of more than 100 proteins that transiently assemble during mitosis at a single epigenetically defined region on each chromosome, known as the centromere.

Identification of senescence‐related genes in Parkinson's disease reveals candidate therapeutic targets and pathological processes

Animal Models and Experimental Medicine, EarlyView.
At the genomic level, a large number of differentially expressed genes (DEGs) and aging‐related DEGs have been screened. Ten hub genes, such as IFNγ and IRF7, have been identified and shown potential value in the diagnosis of PD, holding promise as novel biomarkers to facilitate early and precise diagnosis.

Poleward force at the kinetochore in metaphase depends on the number of kinetochore microtubules. [PDF]

The Journal of cell biology, 1990
To examine the dependence of poleward force at a kinetochore on the number of kinetochore microtubules (kMTs), we altered the normal balance in the number of microtubules at opposing homologous kinetochores in meiosis I grasshopper spermatocytes at metaphase with a focused laser microbeam.

Phosphorylation of Sli15 by Ipl1 is important for proper CPC localization and chromosome stability in Saccharomyces cerevisiae [PDF]

, 2014
The chromosomal passenger complex (CPC) is a key regulator of eukaryotic cell division, consisting of the protein kinase Aurora B/Ipl1 in association with its activator (INCENP/Sli15) and two additional proteins (Survivin/Bir1 and Borealin/Nbl1). Here we

Immune Complexes Shape the Pathogenicity of Autoantibodies in Systemic Autoimmune Diseases: Insights From an FcγRIIIA‐Reporter Assay

Arthritis &Rheumatology, EarlyView.
Objective Immune complexes (ICs), formed by autoantigen and autoantibody, play a pathogenic role in systemic autoimmune diseases through stimulation of Fcγ receptors (FcγR). However, studies investigating bioactivity of circulating ICs across various diseases remain limited.

Recombinant Monoclonal Antibodies for Detecting the Tubulin Post‐Translational Modifications Glutamylation and Lysine‐40 Acetylation

Cytoskeleton, EarlyView.
ABSTRACT Post‐translational modifications (PTMs) to tubulin subunits in microtubule filaments are thought to comprise a component of the tubulin code that specifies microtubule functions in cell physiology and animal development. Acetylation of Lysine‐40 (K40) on α‐tubulin (αTub‐K40ac) and glutamylation of both α‐ and β‐tubulin are two tubulin PTMs of ...

Studying the structure of vertebrate kinetochore using a high-resolution microscopy approach [PDF]

, 2016
The kinetochore is a highly complex proteinaceous structure located at the primary constriction of mitotic chromosomes. Here, it performs an essential role in accurate chromosome segregation.
