TET Enzymes

TET enzymes are a family of dioxygenases that are involved in the process of oxidizing methylated cytosine. Members of this family include ten-eleven translocation methylcytosine dioxygenase 1 (TET1), methylcytosine dioxygenase TET2, and methylcytosine dioxygenase TET3. The gene for the first of these proteins, TET1, was identified when it was determined to be fused to the Mixed Lineage Leukemia (MLL) gene as a result of a translocation event that occurred between chromosomes ten and eleven (hence the name). ^[1]
