Ctcf myc
CCCTC-Binding factor or CTCF was initially discovered as a negative regulator of the chicken c-myc gene. This protein was found to be binding to three regularly spaced repeats of the core sequence CCCTC and thus was named CCCTC binding factor. WebMutational analysis of the P2-proximal CTCF-binding site and transient cotransfection experiments demonstrated that CTCF transcriptionally repressed the human MYC gene. Although there is 100% sequence identity in the DNA-binding domains of the avian and human CTCF proteins, the regulatory sequences recognized by CTCF in chicken and …
