Relevant members of the family, TRP-2 directly participates in the The colorless eumelanin medium, 5,6-dihydroxyindole-2-carboxylicĪcid (DHICA), by TRP-2, and hence, TRP-2 has been named dopachrome Dopa red pigment compounds may be isomerized to Valverde et al ( 9) demonstrated that the molecular weight The TRP-2 carboxyl-terminal and membrane structure domain serve a TRP-2 contains at least eight exons and seven ForĬertain diseases, including albinism and vitiligo, TRP-2 exhibits Is one of the key enzymes involved in melanin synthesis. The early stages of TYR catalytic activity in melanin formation and In animals with woolly coats, TRP-2 may serve an important role in Hair, in addition to the bark of certain plants and insect shells.

With various proteins and is present in human and animal skin and TRP-2 participates in the synthesis of melanin, which interacts Gene family, in terms of protein sequences, exhibiting theĬonserved structure of the TYR family ( 4, 5). TRP-1 and TRP-2 are similar to TYR, which also belongs to the TYR TRP-1 and TRP-2 are members of theįamily of dinuclear copper-binding proteins and contain two highlyĬonserved copper-binding regions ( 1– 3). The tyrosinase (TYR) gene family are derived from aĬommon ancestor, subcategorized into TYR-related protein (TRP)-lĪnd TRP-2 during evolution. The results may provide novel approaches for developing therapeutic strategies for skin diseases associated with pigmentation disorders. Therefore, TRP‑2 may affect melanin production in sheep, and different expression levels determine coat color. TRP‑2 overexpression may regulate melanogenesis and significantly increase melanogenesis associated transcription factor expression in vitro. TRP‑2 expression levels in dark‑colored areas were significantly increased compared with light‑colored areas in piebald sheep. Results revealed differing TRP‑2 levels in sheep of different coat colors and in various parts of the coat with different colors in the same sheep. TRP‑2 was overexpressed in melanocytes in order to study the effect of TRP‑2 on melanin production. In the present study, a skin transcriptome profile, immunohistochemistry, western blotting and reverse transcription‑quantitative polymerase chain reaction were used to investigate TRP‑2 expression in sheep with different coat colors, namely, black, white and black‑white.
