Enables 2-oxoglutarate-dependent dioxygenase activity and cytosine C-5 DNA demethylase activity. Predicted to be involved in DNA dealkylation; cell population proliferation; and oxidative single-stranded RNA demethylation. Predicted to act upstream of or within cellular response to DNA damage stimulus. Predicted to be located in cytosol; mitochondrion; and nucleoplasm. Predicted to be active in nucleus. Orthologous to human ALKBH3 (alkB homolog 3, alpha-ketoglutarate dependent dioxygenase). [provided by Alliance of Genome Resources, Apr 2022]
