Effective dynamics of nucleosome configurations at the yeast PHO5 promoter
Chromatin dynamics are mediated by remodeling enzymes and play crucial roles in gene regulation, as established in a paradigmatic model, the Saccharomyces cerevisiae PHO5 promoter. However, effective nucleosome dynamics, that is, trajectories of promoter

Dynamic de novo heterochromatin assembly and disassembly at replication forks ensures fork stability
Chromatin is dynamically reorganized when DNA replication forks are challenged. However, the process of epigenetic reorganization and its implication for fork stability is poorly understood.

H2A mono-ubiquitination differentiates FACT’s functions in nucleosome assembly and disassembly
The histone chaperone FACT (FAcilitates Chromatin Transcription) plays an essential role in transcription and DNA replication by its dual functions on nucleosome assembly to maintain chromatin integrity and nucleosome disassembly to destabilize ...

Nucleosome proteostasis and histone turnover
Maintenance of protein folding homeostasis, or proteostasis is critical for cell survival as well as for execution of cell type specific biological processes such as muscle cell contractility, neuronal synapse and memory formation, and cell transition ...

The assembly of mammalian SWI/SNF chromatin remodeling complexes is developmentally programed, and loss/mutations of SWI/SNF subunits alter the levels of other components through proteolysis, causing cancers.

Mitochondrial cytochrome c shot towards histone chaperone condensates in the nucleus
Despite mitochondria being key for the control of cell homeostasis and fate, their role in DNA damage response is usually just regarded as an apoptotic trigger.

ATP-dependent chromatosome remodeling [PDF]
Chromatin serves to package, protect and organize the complex eukaryotic genomes to assure their stable inheritance over many cell generations. At the same time, chromatin must be dynamic to allow continued use of DNA during a cell's lifetime.

FACT prevents the accumulation of free histones evicted from transcribed chromatin and a subsequent cell cycle delay in G1. [PDF]
The FACT complex participates in chromatin assembly and disassembly during transcription elongation. The yeast mutants affected in the SPT16 gene, which encodes one of the FACT subunits, alter the expression of G1 cyclins and exhibit defects in the G1/S ...

The histone chaperones Nap1 and Vps75 bind histones H3 and H4 in a tetrameric conformation [PDF]
Histone chaperones physically interact with histones to direct proper assembly and disassembly of nucleosomes regulating diverse nuclear processes such as DNA replication, promoter remodeling, transcription elongation, DNA damage, and histone variant ...

Nucleosome wrapping states encode principles of 3D genome organization. [PDF]
Nucleosome is the basic structural unit of the genome. During processes like DNA replication and gene transcription, the conformation of nucleosomes undergoes dynamic changes, including DNA unwrapping and rewrapping, as well as histone disassembly and ...
