背景信息

CTCF (CCCTC-binding factor) is a highly conserved zinc-finger protein critical for chromatin organization and gene regulation. It functions as a versatile architectural protein, mediating chromatin looping to establish 3D genome structures like topologically associating domains (TADs). CTCF also acts as an insulator, preventing inappropriate enhancer-promoter interactions, and participates in X-chromosome inactivation, genomic imprinting, and chromatin barrier formation. Its binding sites serve as genomic anchors for maintaining nuclear compartmentalization.

CTCF antibodies are essential tools for studying these mechanisms. Widely used in chromatin immunoprecipitation (ChIP-seq), they map genome-wide CTCF binding sites to analyze its regulatory roles. In immunofluorescence and Western blotting, these antibodies help visualize CTCF's nuclear localization and protein expression levels. Commercial CTCF antibodies are typically developed in rabbit or mouse hosts, validated for specificity across applications.

Dysregulation of CTCF is linked to developmental disorders and cancers, making its antibodies valuable for investigating disease mechanisms. Research using CTCF antibodies has revealed mutations and epigenetic alterations affecting CTCF function in tumors, highlighting its role as a tumor suppressor. Standardized validation protocols remain crucial due to variability in antibody performance across experimental conditions.
