**Background of Recombinant Human JARID2 Protein**
JARID2 (Jumonji/AT-rich interaction domain-containing protein 2) is a chromatin-associated protein critical for epigenetic regulation, primarily known for its role in modulating the activity of Polycomb Repressive Complex 2 (PRC2). PRC2 catalyzes histone H3 lysine 27 trimethylation (H3K27me3), a key epigenetic mark involved in gene silencing during development and differentiation. JARID2 acts as a molecular scaffold, facilitating PRC2 recruitment to target genes and fine-tuning its enzymatic activity, thereby ensuring proper embryonic development, cell fate determination, and tissue homeostasis.
Recombinant human JARID2 protein is engineered using expression systems like *E. coli* or mammalian cells, enabling large-scale production for functional studies. Its structure includes conserved domains such as the JmjC domain (lacking catalytic activity) and ARID/BRIGHT domain, which mediate protein-DNA and protein-protein interactions. Studies using recombinant JARID2 have elucidated its role in stem cell pluripotency, X-chromosome inactivation, and carcinogenesis, with dysregulation linked to cancers and neurodevelopmental disorders.
Research on recombinant JARID2 also explores its potential as a therapeutic target or tool for manipulating PRC2-dependent epigenetic pathways. Its application spans chromatin remodeling assays, drug screening, and mechanistic studies of developmental diseases, underscoring its importance in both basic and translational biomedical research.
