Background

TET (Ten Eleven Translocation) family proteins are cytosine oxygenases that catalyze the conversion of 5-methylcytosine (5mC) into 5-hydroxymethylcytosine (5hmC). 5hmC can be further oxidized into 5-formylcytosine (5fC) and 5-carboxylcytosine (5caC) 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 initiating the enzymatic deamination process leading to cytosine demethylation.

TET3 plays an important role in DNA methylation reprogramming processes in the mammalian zygote. TET3 may also contribute to somatic cell nuclear reprogramming during animal cloning. Both of CXXC domain and catalytic domain are important for TET3 regulating key genes of Xenopus eye and neural development.

Application Notes

Recombinant TET3 (824-1795) protein is suitable for use in cytosine oxygenase assays, enzyme kinetics, inhibitor screening, and selectivity profiling.

TET Activity Assay Conditions: 250 nM of 30bp DNA oligos (sequence: 5'-CAGTAACTGTGGTC(mC)GGTAACTGACTTGCA-3', contains a 5mCpG site) was incubated with 100 nM recombinant TET3 (824-1795) protein in buffer containing 50 mM HEPES, pH 8.0, 100 μM Fe(NH4)2(SO4)2, 2 mM ascorbate, 1 mM alpha-ketoglutarate, 1 mM ATP, 1 mM TCEP at 37C for 1 hr. Activity was detected by Dot-blot.
