USP49 deubiquitinase regulates the mitotic spindle checkpoint and prevents aneuploidy
Cell Death and Disease, 2023 The spindle assembly checkpoint (SAC) is an essential mechanism that ensures the accurate chromosome segregation during mitosis, thus preventing genomic instability.

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 ...

No stretch for spindle assembly checkpoint [PDF]
The Journal of Cell Biology, 2008 ![][1] Kinetochores (red) attach to the spindle (green), whereas chromatin (blue) is largely excluded. Dividing cells aren't quite as obsessed with quality control as previously thought, according to results from [O'Connell and colleagues][2].

Prevention of Early Onset of Breast Cancer With Ashwagandha
Molecular Carcinogenesis, EarlyView.ABSTRACT Prevention of breast cancer is feasible because many risk factors for this malignancy are known (e.g., family history, reproductive factors, etc.). Medicinal plants and/or their bioactive phytochemicals are attractive for the prevention of early onset of breast cancer due to their generally favorable safety profile.

Sds22 regulates aurora B activity and microtubule-kinetochore interactions at mitosis [PDF]
, 2010 We have studied Sds22, a conserved regulator of protein phosphatase 1 (PP1) activity, and determined its role in modulating the activity of aurora B kinase and kinetochore-microtubule inter-actions.

Analysis of Mph1 kinase and its substrates in spindle checkpoint signalling [PDF]
, 2010 Accurate chromosome segregation is crucial as mis-segregation results in aneuploidy, which can lead to severe diseases such as cancer. The spindle checkpoint monitors sister-chromatid attachment and inhibits the onset of anaphase until all chromosomes ...

Insights into mitotic checkpoint by integrating CRISPR and RNAi
Molecular & Cellular Oncology, 2019 Our recent study of the mitotic checkpoint protein BUB1 (budding uninhibited by benzimidazoles 1) revealed several apparent BUB1 knock-out cell lines expressing low levels of BUB1 protein sufficient to support spindle assembly checkpoint activity.

Protein Glutamylation: From Cytoskeleton to Signaling
Med Research, EarlyView.Tubulin glutamylation, γ‐glutamylation, and nontubulin glutamylation are distinct yet interconnected post‐translational modifications that regulate diverse physiological and pathological processes, including cytoskeletal organization, cell cycle progression, immunity, metabolism, and disease development.

Cell Reports, 2018 Summary: Faithful chromosome segregation during mitosis depends on the spindle assembly checkpoint (SAC), which delays progression through mitosis until every chromosome has stably attached to spindle microtubules via the kinetochore.

Proteins: Structure, Function, and Bioinformatics, EarlyView.ABSTRACT Allosteric communication is fundamental to the function of proteins, but identifying the residue‐level pathways through which signals travel and their directionality is still a major challenge. Here we present a multi‐metric information‐theoretic framework that identifies candidate allosteric communication pathways from a single protein ...
