Tet1 | Methylcytosine dioxygenase TET1; 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. 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 transcription [...] (2039 aa) | ||||
Spns2 | Protein spinster homolog 2; Acts a a crucial lysosphingolipid sphingosine 1-phosphate (S1P) transporter involved in S1P secretion and function. S1P is a bioactive signaling molecule that regulates many physiological processes important for the development and for the immune system. Regulates levels of S1P and the S1P gradient that exists between the high circulating concentrations of S1P and low tissue levels that control lymphocyte trafficking. (549 aa) |
