TYRP2

TYRP2 stands for Tyrosine-Related Protein 2 an L-dopachrome tautomerase that plays a role in melanin biosynthesis (Pennamen P et al. 2021). The protein is encoded by the DCT gene, which is located on chromosome 13q32.1. TRYP2 catalyzes the conversion of L-dopachrome to 5,6-dihydroxyindole-2-carboxylic acid (DHICA). The encoded protein is thought to enable dopachrome isomerase activity. It is involved in the response to blue light. Located in intracellular, membrane-bound organelles and in the plasma membrane. Diseases associated with DCT include oculocutaneous albinism, type VIII (OCA8).
