Recombinant Human CTCF Protein，His

CTCF (CCCTC-binding factor) is a highly conserved zinc-finger protein that plays a crucial role in regulating gene expression, chromatin organization, and enhancer-promoter interactions. First identified as a transcriptional repressor, CTCF's functions have expanded to include acting as a chromatin insulator, which helps demarcate active and inactive genomic regions, effectively organizing the three-dimensional architecture of the genome. Its ability to bind to specific DNA sequences allows CTCF to form loops in the chromatin, facilitating communication between enhancers and their target promoters. Research into CTCF has revealed its importance in various biological processes, including development, differentiation, and cellular response to stimuli. Abnormal CTCF function has been implicated in several diseases, including cancer, where disruptions in its regulatory roles may lead to aberrant gene expression. Understanding the mechanisms by which CTCF mediates chromatin structure and gene regulation is pivotal for elucidating its role in health and disease, making it a significant focus of current molecular and genomic research. Investigations into CTCF's complex interactions with other proteins, RNAs, and DNA, as well as its involvement in epigenetic modifications, continue to unveil the multifaceted roles this essential protein plays in maintaining genomic integrity and influencing gene activity.
