**Background of CHD4 Recombinant Protein**
Chromodomain Helicase DNA-binding protein 4 (CHD4) is a member of the CHD family of ATP-dependent chromatin remodelers, which play pivotal roles in regulating gene expression by modifying chromatin structure. CHD4 serves as the catalytic core of the Nucleosome Remodeling and Deacetylase (NuRD) complex, linking chromatin remodeling to histone deacetylation and transcriptional repression. It contains conserved domains, including two chromodomains for methyl-lysine binding, a helicase domain for ATP hydrolysis, and a DNA-binding domain, enabling its interaction with nucleosomes and epigenetic modifiers.
CHD4 is critical for embryonic development, DNA damage repair, and cell cycle regulation. Dysregulation of CHD4 is implicated in cancers, neurodevelopmental disorders, and cardiovascular diseases. For instance, CHD4 mutations are linked to aggressive malignancies and rare syndromes like Sifrim-Hitz-Weiss syndrome.
Recombinant CHD4 proteins are engineered to study its biochemical and functional properties. Produced via heterologous expression systems (e.g., *E. coli* or mammalian cells), these proteins retain enzymatic activity and structural integrity, enabling *in vitro* studies on chromatin remodeling mechanisms, protein interactions, and inhibitor screening. Tagged versions (e.g., His, GST) facilitate purification and detection. Research using CHD4 recombinant proteins has advanced understanding of epigenetic regulation and holds promise for developing therapies targeting CHD4-associated diseases.
In summary, CHD4 recombinant proteins are vital tools for dissecting its role in chromatin dynamics and disease, offering insights into precision medicine strategies.
