Dopachrome tautomerase (DCT) is an enzyme that plays a crucial role in the melanogenesis pathway, which is the process of melanin production. DCT catalyzes the conversion of dopachrome to 5,6-dihydroxyindole-2-carboxylic acid (DHICA), and it is a part of the tyrosinase enzyme family. This enzyme is primarily expressed in melanocytes, the cells responsible for pigment production in the skin, hair, and eyes.
