**Background of NCOR2 Recombinant Protein**
The nuclear receptor corepressor 2 (NCOR2), also known as SMRT (Silencing Mediator for Retinoid and Thyroid hormone receptors), is a key regulatory protein involved in transcriptional repression. It functions as a corepressor for nuclear receptors (e.g., thyroid hormone receptors, retinoic acid receptors) and other transcription factors, modulating gene expression by recruiting histone deacetylase (HDAC)-containing complexes to chromatin. This interaction promotes chromatin condensation and suppresses target gene transcription. Structurally, NCOR2 contains multiple domains, including receptor-binding motifs at the N-terminus and repression domains at the C-terminus that mediate interactions with HDACs and other corepressors.
NCOR2 plays critical roles in development, metabolism, and cellular differentiation. It acts as a signaling node in pathways such as Notch, Wnt, and NF-κB, influencing processes like apoptosis, inflammation, and hormone response. Dysregulation of NCOR2 is linked to diseases, including cancers (e.g., leukemia, breast cancer), metabolic syndromes, and neurological disorders. For instance, mutations or altered expression of NCOR2 can disrupt its ability to repress oncogenic transcription factors, contributing to tumor progression.
Recombinant NCOR2 proteins are engineered to study its molecular interactions, structural dynamics, and functional mechanisms. Produced via heterologous expression systems (e.g., *E. coli* or mammalian cells), these proteins often include tags (e.g., GST, His) for purification and detection. Researchers utilize NCOR2 recombinant proteins to map binding interfaces, analyze post-translational modifications (e.g., phosphorylation), and screen for small molecules targeting NCOR2-associated pathways. Such studies provide insights into therapeutic strategies for diseases driven by NCOR2 dysregulation, emphasizing its potential as a biomarker or drug target.
In summary, NCOR2 recombinant proteins are vital tools for unraveling its complex role in gene regulation and disease, bridging structural biology with translational research.
