Target data

Function

Core component of nucleosome. Nucleosomes wrap and compact DNA into chromatin, limiting DNA accessibility to the cellular machineries which require DNA as a template. Histones thereby play a central role in transcription regulation, DNA repair, DNA replication and chromosomal stability. DNA accessibility is regulated via a complex set of post-translational modifications of histones, also called histone code, and nucleosome remodeling.

Supplementary info

Biological function summary

Histone H3 participates in chromatin remodeling and gene transcription regulation. As part of the nucleosome complex it influences DNA accessibility and subsequently gene expression. Through post-translational modifications including methylation and phosphorylation H3 modulates chromatin structure. Common modifications include mono- di- and tri-methylation at various lysine residues like K56 which affect transcriptional activation or repression. These modifications form a part of the histone code a framework for regulating chromatin dynamics and genetic information.

Activity summary

Histone H3 is a core component of the nucleosome playing an important role in DNA packaging within eukaryotic cells. Often referred to as H3 it has a molecular weight of around 15 kDa. Histone H3 is expressed in the nucleus of nearly all eukaryotic cells where it interacts with DNA and other histone proteins to form chromatin structure. Scientists frequently study histone H3 using techniques like Western blotting and immunohistochemistry utilizing antibodies such as anti-histone or phospho-histone H3 to distinguish post-translational modifications.

Pathways

Histone H3 modifications are integral to several signaling pathways that modulate gene expression and cellular responses. The histone code interpreted by other proteins such as transcription factors and chromatin remodelers contributes significantly to the regulation of the cell cycle and signal transduction pathways like the MAPK/ERK pathway. H3 interacts closely with regulatory proteins including other histones and transcription machinery to facilitate these complex processes.

Associated diseases and disorders

Histone H3 modifications are associated with various health conditions including cancer and neurological disorders. Aberrations in histone H3 methylation are linked to oncogenic transformations with disruptions often found in cancer types like glioblastoma and breast cancer. The alterations in H3 also connect to Alzheimer's disease through interactions with other histone modifications and their impact on gene expression patterns critical for neural function. Understanding these modifications helps provide insights into disease mechanisms and potential therapeutic targets.
