WebIn summary, the deletion of four different anchors of four differential loops led to an impaired vitamin D induction of vitamin D target genes inside the respective loop. Also, the CTCF loop anchor deletion caused a gain, loss or increase of vitamin D responsiveness of some genes outside of the 1,25(OH) 2 D 3-sensitive loops. DISCUSSION Transcriptional repressor CTCF also known as 11-zinc finger protein or CCCTC-binding factor is a transcription factor that in humans is encoded by the CTCF gene. CTCF is involved in many cellular processes, including transcriptional regulation, insulator activity, V(D)J recombination and regulation of … See more 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 … See more The primary role of CTCF is thought to be in regulating the 3D structure of chromatin. CTCF binds together strands of DNA, thus forming chromatin loops, and anchors DNA to cellular structures like the nuclear lamina.
