WebThe IGF2 gene provides instructions for making a protein called insulin-like growth factor 2. This protein plays an essential role in growth and development before birth. Studies … WebWhen CTCF is bound to the ICR and DMR, dimerization of CTCF occurs, allowing looping of the DNA containing the gene to take place. This causes the transcription of the gene to be turned [ Select] 9. When CTCF is unable to bind this causes the transcription of the gene to be turned [Select 1 llele of Igf2 i [ Select] methylated not methylated ...
WebApr 15, 2016 · The role of the zinc finger protein CTCF in organizing the genome within the nucleus is now well established.
