Tetrameric organization of vertebrate centromeric nucleosomes
, 2010 Mitosis ensures equal genome segregation in the eukaryotic lineage. This process is facilitated by microtubule attachment to each chromosome via its centromere.

The Sequence Dependent Nanoscale Structure of CENP-A Nucleosomes
, 2022 CENP-A is a histone variant found in high abundance at the centromere in humans. At the centromere, this histone variant replaces the histone H3 found throughout the bulk chromatin.

Journal of the Chinese Chemical Society, EarlyView.Model for how α‐syn modulates the positioning of endolysosomes in melanoma cells. (a) α‐syn tethers endolysosomes to the plasma membrane, a last step in anterograde transport. (b) Loss of α‐syn expression causes the loss of the tethering function, which leads to perinuclear vesicle clustering. Reproduced from the open access article.

Journal of Clinical Laboratory Analysis, EarlyView.This investigation was conducted in two phases. Phase I involved the classification and clinical profiling of AC‐30. In Phase II, quantitative image analysis was performed to explore its associations with clinical parameters. ABSTRACT Background The International Consensus on ANA Patterns (ICAP) recently codified the AC‐30 nuclear pattern ...

Centromeric Nucleosomes Induce Positive DNA Supercoils
, 2009 SummaryCentromeres of higher eukaryotes are epigenetically maintained; however, the mechanism that underlies centromere inheritance is unknown. Centromere identity and inheritance require the assembly of nucleosomes containing the CenH3 histone variant ...

Recent Advances in Photocatalyst‐Driven Protein Labeling and Proximity Mapping
The Chemical Record, EarlyView.Photocatalyst‐driven protein labeling and proximity mapping have rapidly advanced as powerful strategies for spatiotemporal control in complex biological environments. This review integrates recent developments across single‐electron transfer and energy transfer‐based mechanisms and highlights how catalyst design, reactive intermediates, and diffusion ...

Evaluation of nucleosome forming potentials (NFPs) of forensically important STRs
, 2011 Degraded forensic samples have proved difficult to analyze and interpret. New analysis techniques are constantly being discovered and improved but researchers have overlooked the structural properties that could prevent or slow the process of degradation.

Andrology, EarlyView.Abstract Background Myocyte enhancer factor 2 transcription factors regulate essential transcriptional programs in various cell types. The activity of myocyte enhancer factor 2 factors is modulated through interactions with cofactors, chromatin remodelers, and other regulatory proteins, which are dependent on cell context and physiological state.

Histone Tail Dynamics in Partially Disassembled Nucleosomes During Chromatin Remodeling
Frontiers in Molecular Biosciences, 2019 Nucleosomes are structural units of the chromosome consisting of DNA wrapped around histone proteins, and play important roles in compaction and regulation of the chromatin structure.
