function:Transcriptional repressor binding to promoters of vertebrate c-myc gene. Also binds to the PLK and PIM1 promoters. May prevent the access of transcriptional activators to enhancers. Also acts as a transcriptional activator of APP. Involved in different aspects of gene regulation including promoter activation or repression, hormone-responsive gene silencing, methylation-dependent chromatin insulation, and genomic imprinting. Seems to act as tumor suppressor.,similarity:Belongs to the CTCF zinc-finger protein family.,similarity:Contains 11 C2H2-type zinc fingers.,subunit:Interacts with CHD8.,tissue specificity:Ubiquitous. Absent in primary spermatocytes.,
Nucleus, nucleoplasm . Chromosome . Chromosome, centromere . May translocate to the nucleolus upon cell differentiation. Associates with both centromeres and chromosomal arms during metaphase. Associates with the H19 ICR in mitotic chromosomes. May be preferentially excluded from heterochromatin during interphase.
Ubiquitous. Absent in primary spermatocytes.
