Ctcf zinc fingers
WebThe 11 zinc fingers (ZFs) of the transcription factor CTCF play a versatile role in the regulation of gene expression. CTCF binds to numerous genomic sites to form chromatin … WebCTCF is a ubiquitous 11 zinc finger (ZF) protein with highly versatile functions. 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.
