**Background of Hist1h2bm Recombinant Protein**
Hist1h2bm (Histone Cluster 1. H2Bm) is a member of the histone H2B family, which plays a critical role in chromatin structure and epigenetic regulation. Histones are highly conserved proteins that organize DNA into nucleosomes, the fundamental units of chromatin. Each nucleosome consists of an octamer of core histones (two each of H2A, H2B, H3. and H4) around which DNA is wrapped. H2B histones, including Hist1h2bm, contribute to nucleosome stability and participate in DNA repair, replication, and transcriptional regulation through post-translational modifications (e.g., acetylation, methylation) or interactions with chromatin-remodeling complexes.
The *Hist1h2bm* gene is part of the histone gene cluster located on chromosome 13 in mice and chromosome 6 in humans. Recombinant Hist1h2bm protein is typically produced using expression systems like *Escherichia coli* or mammalian cell cultures, enabling controlled production of the protein with high purity. This recombinant form often includes affinity tags (e.g., His-tag) to facilitate purification and detection.
Studies involving Hist1h2bm recombinant protein focus on elucidating its structural interactions within nucleosomes, its role in gene expression modulation, and its involvement in diseases such as cancer, where histone dysregulation is common. Additionally, it serves as a tool for developing antibodies, studying histone exchange dynamics, or reconstituting chromatin in vitro for biochemical assays. Its recombinant availability enhances research precision in epigenetics and molecular biology, offering insights into chromatin-related mechanisms and therapeutic targets.
