CTCF (CCCTC-binding factor) is a highly conserved zinc finger protein critical for organizing 3D genome architecture and regulating gene expression. It mediates chromatin looping, insulates transcriptional domains, and establishes boundaries between active and repressive chromatin regions. CTCF antibodies are essential tools for studying these functions through techniques like chromatin immunoprecipitation (ChIP-seq), which maps genome-wide binding sites, and chromosome conformation capture (3C-based methods) that visualize chromatin interactions.
First developed in the early 2000s, CTCF antibodies have become indispensable in epigenetics research. They enable the investigation of CTCF's role in X-chromosome inactivation, genomic imprinting, and V(D)J recombination. Commercial antibodies are typically raised against specific epitopes (N-terminal, C-terminal, or central regions) and require rigorous validation via knockout controls, given CTCF's multiple isoforms and post-translational modifications.
These antibodies have revealed CTCF's involvement in diseases, particularly cancer, where disrupted CTCF binding correlates with oncogene activation and tumor suppressor silencing. Recent studies also link CTCF dysregulation to neurological disorders and developmental defects. Proper antibody characterization remains crucial, as batch variability can impact data reproducibility in chromatin interaction studies.
