RBBP7 (Retinoblastoma-Binding Protein 7), also known as RbAp46. is a conserved eukaryotic protein belonging to the WD40 repeat protein family. It plays a critical role in chromatin remodeling and epigenetic regulation by interacting with histone complexes and chromatin-modifying enzymes. Structurally, it contains multiple WD40 domains that facilitate protein-protein interactions, enabling its integration into multi-subunit complexes like the NuRD (Nucleosome Remodeling and Deacetylase) complex and PRC2 (Polycomb Repressive Complex 2). These complexes are essential for histone deacetylation, DNA methylation, and gene silencing, influencing cellular processes such as cell cycle regulation, differentiation, and apoptosis.
Recombinant RBBP7 is produced in vitro using expression systems (e.g., E. coli or mammalian cells) to study its molecular functions without endogenous interference. Its recombinant form retains the ability to bind histones H3 and H4. making it valuable for investigating chromatin dynamics, histone modification crosstalk, and epigenetic inheritance. Studies link RBBP7 dysregulation to cancer progression, neurodegenerative diseases, and developmental disorders, positioning it as a potential therapeutic target. For example, its overexpression in certain cancers correlates with aberrant cell proliferation, while reduced levels may impair neuronal development.
Researchers utilize recombinant RBBP7 in assays to dissect its role in DNA repair, X-chromosome inactivation, and stem cell pluripotency. It also serves as a molecular tool for drug screening aimed at modulating epigenetic enzymes. Quality-controlled batches ensure consistency in biochemical studies, with purity and activity validated via SDS-PAGE, western blotting, and binding assays. Overall, RBBP7 recombinant protein bridges structural biology and disease mechanism research, offering insights into epigenetics-driven pathologies.
