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.
