Predicted to enable dopachrome isomerase activity. Predicted to be involved in melanin biosynthetic process from tyrosine and response to blue light. Predicted to act upstream of or within several processes, including developmental pigmentation; generation of neurons; and melanin biosynthetic process. Predicted to be located in cytosol; melanosome; and plasma membrane. Human ortholog(s) of this gene implicated in oculocutaneous albinism. Orthologous to human DCT (dopachrome tautomerase).
