Goat polyclonal, epitope mapping near the C-terminus of CTCF of human origin. Antibody Target: CTCF
Transcriptional regulator with 11 highly conserved zinc finger domains. Depending on context, can bind a histone acetyltransferase (HAT)-containing complex and function as transcriptional activator or bind a histone deacetylase (HDAC)-containing complex and function as transcriptional repressor. Involved in transcriptional regulation by binding to chromatin insulators and preventing interaction between promoter and nearby enhancers and silencers. Preferentially interacts with unmethylated DNA, preventing spreading of CpG methylation. Can dimerize, mediating long-range chromatin looping. When bound to chromatin, provides an anchor point for nucleosomes positioning. Involved in sister chromatid cohesion. Associates with both centromeres and chromosomal arms during metaphase and required for cohesin localization to CTCF sites.
