Anti-CTCF Antibody, clone 1.2.1.5.4

NA.41

CTCF, also known as CCCTC-binding factor, contains 11 zinc finger (ZF) binding domains that allow it to bind different DNA target sequences and proteins. This multifunctional protein can act as a transcriptional activator or repressor. As a transcriptional repressor, CTCF, binds to promoters of vertebrate c-myc gene. It also binds to the PLK and PIM1 promoters. CTCF may prevent the access of transcriptional activators to enhancers. CTCF also acts as a transcriptional activator of APP. It is involved in different aspects of gene regulation including promoter activation or repression, hormone-responsive gene silencing, methylation-dependent chromatin insulation, and genomic imprinting. Mutations of CTCF in this gene have been associated with invasive breast cancers, prostate cancers, and Wilms tumors, suggesting a role for CTCF may as a tumor suppressor.

This antibody recognizes CTCF.

Note: Poly(ADP-ribosyl)ated isoform, C-terminal truncation, or sumoylation will cause variable migration of CTCF protein on SDS–PAGE, which may present CTCF with different molecular weight on Western Blot. Modifications are dependent on cell type and growing condition.
The following molecular weights have been reported in the literature: 180 kDa (CTCF-180), 130 kDa (CTCF-130), 82 kDa (CTCF-82), 70 kDa (CTCF-70).
