**Background of CHAF1B Recombinant Protein**
CHAF1B (Chromatin Assembly Factor 1 Subunit B), also known as CAF-1 p60 or CAF1B, is a critical component of the chromatin assembly factor 1 (CAF-1) complex, which plays a central role in DNA replication-coupled chromatin assembly. The CAF-1 complex consists of three subunits: CHAF1A (p150), CHAF1B (p60), and the smallest subunit p48 (RBBP4). CHAF1B acts as a histone chaperone, facilitating the deposition of histones H3 and H4 onto newly synthesized DNA during replication and repair, thereby ensuring proper nucleosome formation and epigenetic inheritance.
Recombinant CHAF1B protein is produced through heterologous expression systems (e.g., *E. coli* or mammalian cells) to study its structure, interactions, and functions in vitro. Its recombinant form retains the ability to bind histones and interact with other CAF-1 subunits, enabling researchers to dissect molecular mechanisms of chromatin assembly, DNA repair, and replication. CHAF1B is essential for cell proliferation, differentiation, and genome stability, and its dysregulation has been implicated in cancers, neurodegenerative diseases, and aging.
Studies using recombinant CHAF1B have advanced understanding of epigenetic regulation, particularly in contexts like stem cell reprogramming and cancer epigenetics. Its role in mediating histone recycling and maintaining chromatin integrity makes it a potential therapeutic target. Recombinant CHAF1B also serves as a tool for screening inhibitors or modulators of chromatin-associated processes, bridging basic research and translational applications.
