Ten Eleven Translocation (TET) family proteins are cytosine oxygenases that catalyze the conversion of 5-methylcytosine (5-mC) into 5-hydroxymethylcytosine (5-hmC). 5-hmC can be further oxidized into 5-formylcytosine (5-fC) and 5-carboxylcytosine (5-caC) by TET proteins. Methylation at the C5 position of cytosine is an epigenetic modification of the mammalian genome that plays an important role in transcriptional regulation. TET proteins are responsible for iinitiating the enzymatic deamination process leading to cytosine demethylation.

The Tet family of dioxygenases is widely distributed across the tree of life, including in the heterolobosean amoeboflagellate Naegleria gruberi . NgTet1 (Naegleria Tet-like protein) is a homologue of mammalian Tet proteins. Like mammalian Tet proteins, NgTet1 acts on 5-mC and generates 5-hmC, 5-fC and 5-caC.

Application Notes

Recombinant NgTet1 protein is suitable for use in cytosine oxygenase assays, 5-mC sequencing, enzyme kinetics, inhibitor screening, and selectivity profiling.

Recombinant NgTet1 activity assay
1 µg of 30 nt ssDNA oligos with a 5mCpG site were incubated with different concentrations of NgTet1 in a reaction system at 34°C for 1 hour. Sample was concentrated to 10 µl, and 1 µl was spotted onto nylon membrane. 5hmC Ab (Cat. No. 39769) and 5-caC Ab (Cat. No. 61225) were used to detect products. NgTet1 activity assay was detected by Dot-Blot..


Recombinant proteins in solution are temperature sensitive and must be stored at -80°C to prevent degradation. Avoid repeated freeze/thaw cycles and keep on ice when not in storage.
