Plays a role in melanin biosynthesis (PubMed:33100333). Catalyzes the conversion of L-dopachrome into 5,6-dihydroxyindole-2-carboxylic acid (DHICA). L-dopachrome = 5,6-dihydroxyindole-2-carboxylate Binds 2 Zn(2+) ions per subunit. Pigment biosynthesis; melanin biosynthesis. Forms an OPN3-dependent complex with TYR in response to blue light in melanocytes. Proper trafficking to melanosome is regulated by SGSM2, ANKRD27, RAB9A, RAB32 and RAB38. Induced by blue light (415nm). Glycosylated. The disease is caused by variants affecting the gene represented in this entry. Belongs to the tyrosinase family.
