H3–H4 histone chaperones and cancer
Current Opinion in Genetics & Development, 2022 Histone chaperones are key regulators of chromatin structure and function. Their frequent mis-regulation in various cancers can impact tumor initiation and progression. Here, we focus on H3-H4 histone chaperones to highlight recent studies concerning their roles in several cancers thereby expanding on previous reports illustrating their functions as ...

ATP-dependent chromatosome remodeling [PDF]
, 2008 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.

Histone chaperone networks shaping chromatin function [PDF]
Nature Reviews Molecular Cell Biology, 2017 The association of histones with specific chaperone complexes is important for their folding, oligomerization, post-translational modification, nuclear import, stability, assembly and genomic localization. In this way, the chaperoning of soluble histones is a key determinant of histone availability and fate, which affects all chromosomal processes ...

The intrinsically disordered distal face of nucleoplasmin recognizes distinct oligomerization states of histones [PDF]
, 2013 The role of Nucleoplasmin (NP) as a H2A-H2B histone chaperone has been extensively characterized. To understand its putative interaction with other histone ligands, we have characterized its ability to bind H3-H4 and histone octamers.

Histone chaperones link histone nuclear import and chromatin assembly [PDF]
Biochimica et Biophysica Acta (BBA) - Gene Regulatory Mechanisms, 2012 Histone chaperones are proteins that shield histones from nonspecific interactions until they are assembled into chromatin. After their synthesis in the cytoplasm, histones are bound by different histone chaperones, subjected to a series of posttranslational modifications and imported into the nucleus.

Proteotoxic stress reprograms the chromatin landscape of SUMO modification [PDF]
, 2015 The small ubiquitin-like modifier 2 (SUMO-2) is required for survival when cells are exposed to treatments that induce proteotoxic stress by causing the accumulation of misfolded proteins.

The histone shuffle: histone chaperones in an energetic dance [PDF]
Trends in Biochemical Sciences, 2010 Our genetic information is tightly packaged into a rather ingenious nucleoprotein complex called chromatin in a manner that enables it to be rapidly accessed during genomic processes. Formation of the nucleosome, which is the fundamental unit of chromatin, occurs via a stepwise process that is reversed to enable the disassembly of nucleosomes.

Emerging roles of telomeric chromatin alterations in cancer [PDF]
, 2019 Telomeres, the nucleoprotein structures that cap the ends of eukaryotic chromosomes, play important and multiple roles in tumorigenesis. Functional telomeres need the establishment of a protective chromatin structure based on the interplay between the ...

Histone acetylation-independent transcription stimulation by a histone chaperone [PDF]
Nucleic Acids Research, 2006 Histone chaperones are thought to be important for maintaining the physiological activity of histones; however, their exact roles are not fully understood. The physiological function of template activating factor (TAF)-I, one of the histone chaperones, also remains unclear; however, its biochemical properties have been well studied.

Nucleus-specific linker histones Hho1 and Mlh1 form distinct protein interactions during growth, starvation and development in Tetrahymena thermophila [PDF]
, 2019 Chromatin organization influences most aspects of gene expression regulation. The linker histone H1, along with the core histones, is a key component of eukaryotic chromatin.
