Recombinant human HIST1H2AI protein is a genetically engineered version of the histone H2A variant encoded by the HIST1H2AI gene. As a core component of nucleosomes, it plays a critical role in chromatin organization, DNA packaging, and epigenetic regulation. Unlike canonical histones, H2A variants like HIST1H2AI exhibit sequence variations that influence nucleosome stability, DNA accessibility, and interaction with chromatin-modifying enzymes. This protein is part of the HIST1 cluster on chromosome 6. which contains multiple replication-dependent histone genes. Its recombinant form is produced using expression systems (e.g., E. coli or eukaryotic cells) to ensure high purity and avoid contamination with native histones, enabling controlled studies. Researchers utilize recombinant HIST1H2AI to investigate chromatin remodeling, transcriptional regulation, and DNA repair mechanisms. It is particularly valuable in studying post-translational modifications (e.g., phosphorylation, ubiquitination) that modulate gene expression and cellular responses to stress. Applications extend to cancer biology, as aberrant histone dynamics are linked to genomic instability and tumorigenesis. The protein's availability also supports drug discovery efforts targeting epigenetic pathways. Characterization typically involves mass spectrometry, western blotting, and functional assays to confirm structural integrity and activity. By providing a standardized reagent, recombinant HIST1H2AI advances mechanistic studies of chromatin biology and disease-related epigenetic dysregulation.
