TYR (Tyrosinase): TYR is an enzyme crucial in the melanin biosynthesis pathway, responsible for the initial steps of converting tyrosine into melanin pigments. Melanin is essential for coloration in the skin, hair, and eyes, and plays a protective role against UV radiation. Mutations in TYR are associated with albinism, a condition characterized by a deficiency or absence of melanin, leading to visual problems and increased skin cancer risk. TYR's function in pigmentation underscores its importance in protecting against UV-induced damage and in normal visual system development. ...
