生化/生理作用

Tyrosinase is a copper-containing enzyme that catalyzes four steps in the melanin and catecholamine synthesis pathways. It catalyzes the formation of L-DOPA (L-3,4-dihydroxyphenylalanine) in the brain and nervous system. It oxidizes monophenols and o-diphenols to o-quinones. The molecular mass is approximately 60 kDa.

While histological analysis represents a powerful tool for the classification of melanocytic lesions as benign or malignant, a clear-cut distinction between a nevus and a melanoma is sometimes a challenging step of the diagnostic process. The immunohistochemical detection of tyrosinase
