**Background of YY1 Recombinant Protein**
Yin Yang 1 (YY1) is a ubiquitously expressed, multifunctional zinc-finger transcription factor that plays a dual role in gene regulation, acting as both a transcriptional activator and repressor depending on cellular context and interacting partners. First identified in the 1990s, YY1 binds to DNA through its conserved zinc-finger domains and regulates a wide array of biological processes, including embryonic development, cell differentiation, proliferation, and apoptosis. It interacts with chromatin-modifying complexes (e.g., Polycomb group proteins, HDACs) and other transcription factors to modulate epigenetic landscapes and gene expression. Dysregulation of YY1 has been implicated in cancers, neurodegenerative diseases, and immune disorders, underscoring its critical role in maintaining cellular homeostasis.
Recombinant YY1 protein is produced using engineered expression systems (e.g., *E. coli* or mammalian cells) to ensure high purity and bioactivity. This engineered version retains the native protein's functional domains, enabling researchers to study its DNA-binding properties, protein-protein interactions, and regulatory mechanisms *in vitro* or in cell-based assays. Recombinant YY1 is widely used in chromatin immunoprecipitation (ChIP), electrophoretic mobility shift assays (EMSAs), and as a control in functional studies exploring its role in disease pathways. Its availability accelerates research into YY1-targeted therapeutic strategies, such as small-molecule inhibitors or gene-editing approaches, to address pathologies linked to YY1 dysfunction. By providing a standardized and scalable source of the protein, recombinant YY1 supports both basic research and drug discovery efforts aimed at understanding its pleiotropic functions in health and disease.
