Members of this family catalyze nucleic acid modifications, such as thymidine hydroxylation during base J synthesis in kinetoplastids [2], and the conversion of 5 methyl-cytosine (5-mC) to 5-hydroxymethyl-cytosine (hmC) [3], or further oxidation to 5-formylcytosine (5fC) and 5-carboxylcytosine (5caC) [4]. Metazoan TET proteins contain a cysteine-rich region inserted into the core of the DSBH fold. Vertebrate TET proteins are oncogenes that are mutated in various myeloid cancers [5]. Fungal and algal versions of this family are linked to a predicted transposase and show lineage-specific expansions [1].
