TYR (Tyrosinase): TYR is an enzyme that plays a key role in the melanin biosynthesis pathway, responsible for the initial steps of converting tyrosine into melanin pigments. Melanin is essential for the coloration of skin, hair, and eyes, and it provides protection against UV radiation. Mutations in TYR are linked to albinism, a condition marked by reduced or absent melanin, which can lead to visual impairments and a higher risk of skin cancer. TYR’s role in pigmentation highlights its importance in shielding against UV damage and supporting normal visual system development.
