Recombinant human H2AFB3 protein is a synthetic form of histone H2A.B3. a variant of the core histone H2A family. Histones are essential chromatin components that organize DNA into nucleosomes and regulate gene expression. H2AFB3. encoded by the H2A.B3 gene, belongs to the H2A.B subfamily, which is testis-specific and evolutionarily conserved in mammals. Unlike canonical H2A histones, H2A.B3 lacks a structured C-terminal tail and contains unique sequence features, including a truncated docking domain, which contributes to its distinct nucleosome stability and DNA unwrapping properties. These structural differences enable H2A.B3 to modulate chromatin dynamics, particularly during spermatogenesis, by promoting transcriptional activation in germ cells.
Recombinant H2AFB3 is typically produced using expression systems like Escherichia coli or mammalian cells, followed by purification via affinity chromatography. Its production facilitates studies on chromatin remodeling, DNA repair, and epigenetic regulation. Research suggests H2A.B3 plays roles in meiotic recombination, post-meiotic chromatin compaction, and transcriptional elongation. Dysregulation of H2AFB3 has been implicated in male infertility and cancer progression, with overexpression observed in certain malignancies. Recombinant H2AFB3 is a key tool for investigating its molecular interactions, post-translational modifications, and therapeutic potential. Its study also aids in understanding the functional divergence of histone variants in development and disease.
