Predicted to enable copper ion binding activity; protein homodimerization activity; and tyrosinase activity. Involved in several processes, including response to UV; response to cAMP; and response to vitamin D. Located in cytosol and nucleus. Used to study oculocutaneous albinism. Human ortholog(s) of this gene implicated in melanoma (multiple); ocular albinism; oculocutaneous albinism (multiple); retinoschisis; and vitiligo. Orthologous to human TYR (tyrosinase).
