WebCTCF. 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. [5] [6] CTCF is involved in many cellular processes, including transcriptional regulation, insulator activity, V (D)J recombination [7] and regulation of chromatin architecture. [8] WebCTCF’s role in tumor suppression is further demonstrated in vivo using CTCF hemizygous knockout mice, which have a significantly higher chance to succumb to different types of cancer including uterine tumors, T cell lymphoma, and B cell lymphoma by 100 weeks of age in comparison to their WT counterparts. Furthermore, CTCF hemizygous knockout ...
