Predicted to enable cysteine dioxygenase activity and ferrous iron binding activity. Predicted to be involved in several processes, including L-cysteine catabolic process; lactation; and response to glucagon. Predicted to act upstream of or within L-cysteine catabolic process to taurine. Located in cytosol. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Orthologous to human CDO1 (cysteine dioxygenase type 1).
