Histone H2a Dioxygenase AlkB Homolog 1

A dioxygenase and alkylation repair homolog that functions by oxidative demethylation in RNA and DNA REPAIR of substrates which contain 3-methylcytosine. It also functions as one of the HISTONE DEMETHYLASES involved in embryonic development and maintaining the pluripotency of EMBRYONIC STEM CELLS.
