Tyrosinase, the key enzyme in melanin synthesis, is expressed specifically in pigment-producing cells. Studies with transgenic mice and gene transfer experiments have demonstrated that the 270-base pair 5'-flanking sequence of the mouse tyrosinase gene lea ...
Tyrosinase is one of the key enzymes in mammalian melanin synthesis. The pigment is produced in two different cell types: the pigmented epithelial cell of the retina, and the melanocyte, a cell of neural-crest origin. We recently showed that a fusion gene ...

The tyrosinase gene family encompasses three members, tyrosinase, tyrosinase-related protein 1 (Tyrp1) and dopachrome tautomerase (Dct), which encode for proteins implicated in melanin synthesis. In human and mouse, genomic organization is known for all th ...

Tyrosinase is the key enzyme in pigment synthesis, initiating a cascade of reactions which convert the amino acid tyrosine to the melanin biopolymer. Two other tyrosinase-related proteins (TRP) are known, TRP-1 (probably DHICAoxidase) and TRP-2 (DOPAchrome ...
Tyrosinase, the key enzyme in melanin synthesis, is expressed in pigment cells derived from both neural crest and neuroectoderm. The present study was performed to detect tyrosinase promoter activity and tyrosinase gene expression during murine brain devel ...
Tyrosinase is the key enzyme in melanin synthesis, and is expressed in the pigment epithelium of the retina, a cell layer derived from the optic cup; and in neural crest-derived melanocytes of skin, hair follicle, choroid, and iris. The tyrosinase gene has ...
Dark-eyed albino (C44H) is a recessive allele at the mouse albino (c) locus, which encodes tyrosinase (monophenol,L-dopa:oxygen oxidoreductase, EC 1.14.18.1), the key enzyme in melanin synthesis. Similar to type IB oculocutaneous albinism in humans, overal ...
Current evidence suggests that melanogenesis is controlled by epidermal paracrine modulators. We have analyzed the effects of transforming growth factor-beta1 (TGF-beta1) on the basal melanogenic activities of B16/F10 mouse melanoma cells. TGF-beta1 treatm ...
Melanin pigments are found in all biological kingdoms. At the cellular level, correct pigmentation depends not only on correct migration of pigment cells (melanocytes) and their precursors (melanoblasts), but also on specialized cytoplasmic organelles, mel ...
Pigment in mammals is produced in melanocytes of the skin derived from the neural crest and in the pigmented epithelial cells of the retina derived from the optic cup. Tyrosinase (monophenol, L-dopa:oxygen oxidoreductase, EC 1.14.18.1) is regarded as the k ...
