**CHRAC1 Recombinant Protein: Background**
The CHRAC1 (Chromatin Accessibility Complex 1) protein is a key component of the CHRAC chromatin remodeling complex, which belongs to the ISWI (Imitation Switch) family of ATP-dependent chromatin remodelers. This complex plays a vital role in regulating chromatin structure and accessibility, influencing DNA replication, repair, and transcriptional regulation. CHRAC1 partners with the ATPase SNF2H (SNF2 histone linker PHD RING helicase) and other subunits (e.g., BAZ1A or BAZ1B) to form a multi-protein assembly that slides nucleosomes along DNA, modulating gene expression by altering chromatin compaction.
Recombinant CHRAC1 protein is engineered using heterologous expression systems (e.g., *E. coli* or mammalian cells) to produce a purified, functional form of the protein for *in vitro* studies. Its production enables researchers to dissect the molecular mechanisms of chromatin remodeling, including nucleosome spacing, histone-DNA interaction dynamics, and coordination with epigenetic modifiers. CHRAC1’s recombinant form is often tagged (e.g., His, FLAG) for purification and detection, ensuring high specificity in assays like chromatin reconstitution, ATPase activity tests, or protein interaction studies.
Research on CHRAC1 recombinant protein contributes to understanding diseases linked to chromatin dysregulation, such as cancers or developmental disorders. It also aids in drug discovery targeting chromatin remodelers. By providing a controlled, scalable source of the protein, recombinant CHRAC1 facilitates structural studies (e.g., cryo-EM) and functional screens, advancing insights into genome organization and epigenetic therapies.
