TYR (human)

Overview
TYR 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. Increased expression after UVB irradiation. Belongs to the tyrosinase family. 2 isoforms of the human protein are produced by alternative splicing. Note: This description may include information from UniProtKB.
