Tacrolimus 80-85 tyrosinase Homo sapiens 89-99 26581186-3 2016 This treatment did not affect the transcription levels of tyrosinase, suggesting that FK506 increases melanin synthesis by regulating cellular levels of tyrosinase. Tacrolimus 86-91 tyrosinase Homo sapiens 153-163 26581186-4 2016 Interestingly, FK506 promoted melanosome maturation by increasing melanosomal pH (a marker of melanosome maturation), thereby enhancing the stability of melanosome-localized tyrosinase. Tacrolimus 15-20 tyrosinase Homo sapiens 174-184
