CTCF a widely expressed, sequence-specific DNA-binding transcriptional regulator, insulator, and organizer of higher-order chromatin structure. Acts as a tumor suppressor. Contains 11 C2H2-type zinc fingers. Involved in promoter activation or repression, hormone-responsive gene silencing, methylation-dependent chromatin insulation, and genomic imprinting. Mediates pairing between X chromosomes and interactions between distant regulatory elements. Binds to promoters of c-myc, PLK, PIM1 and APP. A critical regulator of cell-cycle arrest and death after B cell receptor signaling in immature B cells. CTCF, together with YY1 and Tsix, form a regulated epigenetic switch for X-inactivation.
