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] WebIgf2 (insulin-like growth factor 2) and H19 genes are imprinted in mammals; they are expressed unevenly from the two parental alleles. Igf2 is a growth factor expressed in most normal tissues, solely from the paternal allele. H19 gene is transcribed (but not translated to a protein) from the materna …
