General annotation

Function This is a copper-containing oxidase that functions in the formation of pigments such as melanins and other polyphenolic compounds. Catalyzes the rate-limiting conversions of tyrosine to DOPA, DOPA to DOPA-quinone and possibly 5,6 dihydroxyindole to indole-5'6 quinone. Binds to the surface of hemocytes and is involved in hemocyte melanization.
Subcellular location Secreted.
