Biological function summary
Tet2 participates in the regulation of gene expression through its impact on DNA methylation status. By promoting DNA demethylation Tet2 influences transcriptional networks that are vital for cell differentiation and development. The enzyme functions as part of a larger complex with cofactors including ascorbic acid which it requires for full enzymatic activity. Its actions affect the regulation of important processes such as self-renewal and differentiation in hematopoietic stem cells.
Pathways
The enzymatic activity of Tet2 plays a role in epigenetic pathways involved in hematopoiesis and immune function. In particular Tet2 interacts with pathways regulating chromatin structure and transcriptional control. It associates with proteins like TET1 and TET3 as they share roles in the regulation of 5-hydroxymethylcytosine levels. Through these mechanisms Tet2 contributes significantly to the maintenance of normal hematopoietic and immune cell function.

General info
Function
Dioxygenase that catalyzes the conversion of the modified genomic base 5-methylcytosine (5mC) into 5-hydroxymethylcytosine (5hmC) and plays a key role in active DNA demethylation. Has a preference for 5-hydroxymethylcytosine in CpG motifs. Also mediates subsequent conversion of 5hmC into 5-formylcytosine (5fC), and conversion of 5fC to 5-carboxylcytosine (5caC). Conversion of 5mC into 5hmC, 5fC and 5caC probably constitutes the first step in cytosine demethylation. Methylation at the C5 position of cytosine bases is an epigenetic modification of the mammalian genome which plays an important role in transcriptional regulation. In addition to its role in DNA demethylation, also involved in the recruitment of the O-GlcNAc transferase OGT to CpG-rich transcription start sites of active genes, thereby promoting histone H2B GlcNAcylation by OGT.
Sequence similarities
Belongs to the TET family.
Post-translational modifications
May be glycosylated. It is unclear whether interaction with OGT leads to GlcNAcylation. According to a report, it is not GlcNAcylated by OGT (PubMed:23353889). In contrast, another group reports GlcNAcylation by OGT in mouse ortholog.. Monoubiquitinated at Lys-1299 by the DCX (DDB1-CUL4-X-box) E3 ubiquitin-protein ligase complex called CRL4(VprBP) or CUL4A-RBX1-DDB1-DCAF1/VPRBP complex; this modification promotes binding to DNA.
