Recombinant human HIST1H3E protein is a laboratory-engineered version of the histone H3.4 isoform encoded by the HIST1H3E gene, which belongs to the HIST1 cluster on chromosome 6. As a core component of nucleosomes, histone H3 plays a critical role in chromatin structure and epigenetic regulation by organizing DNA into higher-order structures and modulating gene expression through post-translational modifications (e.g., methylation, acetylation). The HIST1H3E-encoded H3.4 variant is particularly associated with actively transcribed genes and may influence cellular processes such as differentiation and DNA repair. Recombinant production typically involves cloning the HIST1H3E gene into expression systems (e.g., E. coli or mammalian cells), followed by purification to ensure homogeneity. This engineered protein enables standardized studies on histone-mediated epigenetic mechanisms, nucleosome dynamics, and disease-associated mutations (e.g., cancers linked to histone H3 dysregulation). Its availability supports biochemical assays, antibody development, and drug discovery targeting chromatin-related pathways, offering insights into both fundamental biology and therapeutic strategies for epigenetic disorders.
