Enables 2-oxoglutarate-dependent dioxygenase activity and cytosine C-5 DNA demethylase activity. Predicted to be involved in DNA dealkylation involved in DNA repair and oxidative DNA demethylation. Predicted to act upstream of or within cellular response to DNA damage stimulus. Predicted to be located in nucleoplasm. Orthologous to human ALKBH2 (alkB homolog 2, alpha-ketoglutarate dependent dioxygenase). [provided by Alliance of Genome Resources, Apr 2022]
