part of the protein extends into the cytoplasm of the melanocyte. As opposed to fungal tyrosinase, human tyrosinase is a membrane-bound glycoprotein and has 13% carbohydrate content. The derived TYR allele (rs2733832) is associated with lighter skin pigmentation in human populations. It is most common in Europe, but is also found at lower, moderate frequencies in Central Asia, the Middle East, North Africa, and among the San and Mbuti Pygmies. Bacterial In peatlands, bacterial tyrosinases are proposed to act as key regulators of carbon storage by removing phenolic compounds, which inhibit the degradation of organic carbon. Gene regulation The gene for tyrosinase is regulated by the microphthalmia-associated transcription factor (MITF). Clinical significance A mutation in the tyrosinase gene resulting in impaired tyrosinase production leads to type I oculocutaneous albinism, a hereditary disorder that affects one in every 20,000 people. Tyrosinase activity is very important. If uncontrolled during the synthesis of melanin, it results in increased melanin synthesis. Decreasing tyrosinase activity has been targeted for the improvement or prevention of conditions related to the hyperpigmentation of the skin, such as melasma and age spots. Several polyphenols, including flavonoids or stilbenoid, substrate analogues, free radical scavengers, and copper chelators, have been known to inhibit tyrosinase. Henceforth, the medical and cosmetic industries are focusing research on tyrosinase inhibitors to treat skin disorders. Inhibitors Known Tyrosinase inhibitors are the following: Azelaic acid Hydroquinone L-ascorbic acid - Vitamin C Tranexamic acid Genetics While albinism is common, there have only been a few studies about the genetic mutations in the tyrosinase genes of animals. One of them was on Bubalus bubalis (water buffalo). The tyrosinase mRNA sequence of the wild-type B. bubalis is 1,958 base pairs (bp) with an open reading frame (ORF) of 1,593 bp long, which translates to 530 amino acids. Meanwhile, the tyrosinase gene of the albino B. bubalis (GenBank JN_887463) is truncated at position 477, caused by a point mutation in nucleotide 1431 which converts a Tryptophan (TGG) into a stop codon (TGA), resulting in a shorter and inactive tyrosinase gene. Other albinos have point mutations that appear to inactivate Tyrosinase without truncation (see table and figure for examples). Knowing that there are a few studies about the genomic data of the tyrosinase gene, there are only a handful of studies on the mutations in albino amphibians. Miura et al. (2018) investigates the amino acid mutations in the tyrosinase gene in three
