Enables chemoattractant activity and oxidative DNA demethylase activity. Involved in DNA demethylation and tRNA demethylation. Acts upstream of or within several processes, including generation of neurons; negative regulation of neuron apoptotic process; and placenta development. Located in euchromatin. Is expressed in several structures, including branchial arch; central nervous system; gonad; hemolymphoid system gland; and limb bud. Orthologous to human ALKBH1 (alkB homolog 1, histone H2A dioxygenase). [provided by Alliance of Genome Resources, Apr 2022]
