The HIST1H4H gene encodes a member of the histone H4 family, essential components of nucleosomes that organize eukaryotic DNA into chromatin. As one of 11 human H4 histone variants, HIST1H4H plays a fundamental role in chromatin structure regulation and epigenetic mechanisms. Its canonical H4 sequence contains a conserved globular domain and an unstructured N-terminal tail rich in lysine residues, enabling post-translational modifications (e.g., acetylation, methylation) that dynamically influence chromatin accessibility and gene expression patterns.
Recombinant human HIST1H4H protein production typically employs bacterial (e.g., E. coli) or eukaryotic expression systems to achieve proper folding and post-translational modifications. This engineered protein serves as a critical tool for studying nucleosome assembly, histone-DNA interactions, and epigenetic regulation mechanisms. Researchers utilize it in chromatin remodeling assays, antibody validation, and structural biology studies (e.g., X-ray crystallography, cryo-EM). Its recombinant form enables precise control over modification states, facilitating investigations into how specific histone marks regulate cellular processes like transcription, replication, and DNA repair. Current studies focus on its potential dysregulation in cancers and neurological disorders, with emerging applications in drug discovery targeting epigenetic modifiers.
