Mammalian tyrosinase is found specially in melanocytes, which are highly specializedcells locatedinthe skin, hairbulbs, and eyes which produce pigments.
One approach to promote tyrosinase maturation in melanocytes in culture is to increase the levels of tyrosine or L-DOPA, which accounts for an early observation, prior to genetic classification of albinism, that hairbulbs incubated in high levels of tyrosine could indicate whether the type of OCA was tyrosinase-negative (no increase in melanin) or -positive (heavily pigmented hairbulbs post incubation).
