WebH19 is a gene for a long noncoding RNA, found in humans and elsewhere.H19 has a role in the negative regulation (or limiting) of body weight and cell proliferation. This gene also has a role in the formation of some cancers and in the regulation of gene expression. .. The H19 gene is expressed exclusively on one parental allele in a phenomenon known as imprinting. 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 chromatin architecture.
