简介
CTCF protein is a chromatin-binding factor that plays multiple roles in transcriptional regulation and epigenetic control. It binds to DNA at specific sites and acts as a transcriptional repressor by binding to chromatin insulators to prevent undesirable interactions between promoters and neighboring enhancers or silencers. CTCF Protein, Human is the recombinant human-derived CTCF protein, expressed by E. coli , with tag free.

Protein Description
CTCF (CCCTC-binding factor) is a multifunctional zinc finger domain protein that plays a crucial role in the regulation of gene expression, chromatin organization, and the formation of higher-order genomic structures. Identified as a key player in the maintenance of genome integrity, CTCF acts as an insulator to block aberrant enhancer-promoter interactions, thereby ensuring proper transcriptional control. Its binding sites are significantly enriched at the boundaries of topologically associating domains (TADs), which are fundamental units of spatial genome organization. Additionally, CTCF is involved in various biological processes, including cellular differentiation, development, and response to environmental stimuli. Abnormalities in CTCF function and expression have been linked to a range of diseases, including cancer, highlighting its importance in normal cellular physiology. Recent advances in high-throughput sequencing and chromatin conformation capture techniques have provided deeper insights into the dynamic roles of CTCF in shaping the genome architecture and its interactions with other proteins and nucleic acids. As research continues to unravel the complex mechanisms through which CTCF influences gene regulation and chromatin structure, it is becoming increasingly evident that this protein is a central hub in the intricate network governing cellular function and identity. Understanding CTCF's multifaceted roles may pave the way for novel therapeutic strategies targeting gene dysregulation and other associated pathologies.
