for Recombinant TET2 (1129-2002) proteinBackground

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.

TET2 plays an important role in normal myelopoiesis. Somatic loss-of-function mutations in TET2 gene frequently occur in patients with myeloid malignancies. TET2 loss increased hematopoietic stem cell self-renewal and myeloid transformation. TET2 promotes histone O-GlcNAcylation during gene transcription in embryonic stem cells. In addition, TET2 can be recruited to chromatin by CXXC domain protein IDAX. IDAX downregulates TET2 protein by activating caspase pathway.

Recombinant TET2 protein gel.

Recombinant TET2 (1129-2002) protein gel.
Recombinant TET2 (1129-2002) protein was run on an 8% SDS-PAGE gel and stained with Coomassie Blue.

Recombinant TET2 protein activity assay

Recombinant TET2 (1129-2002) protein activity.
250 ng of 30 base oligo (containing 5mCpG) was incubated with 0.3125 µg, 0.625 µg or 1.25 µg TET2 in reaction buffer at 37°C for 1 hour. Sample was concentrated to 5 µl, and 1 µl was spotted onto nylon membrane. Anti-5hmC Ab (Cat#: 39769) was used to detect products.

for Recombinant TET2 (1129-2002) proteinStorage

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.
