Tyrosinase has a wide range of functions in insects, including wound healing, sclerotization, melanin synthesis and parasite encapsulation. As a result, it is an important enzyme as it is the defensive mechanism of insects. Some insecticides are aimed to inhibit tyrosinase. [14]
The catalytic function of Tyrp1 in human melanocytes is less clear. Tyrp1 is involved in stabilizing of tyrosinase protein and modulating its catalytic activity. [7] Tyrp1 is also involved in maintenance of melanosome structure and affects melanocyte proliferation and melanocyte cell death. [9]
Tyrosine kinases function in a variety of processes, pathways, and actions, and are responsible for key events in the body. The receptor tyrosine kinases function in transmembrane signaling, whereas tyrosine kinases within the cell function in signal transduction to the nucleus. [4]
Albinism - Normal number of melanocytes, but decreased melanin production due to decreased tyrosinase activity or defective tyrosine transport; Melasma (Chloasma) - Patchy hyperpigmentation of the skin Normal number of melanocytes with increased melanin production causing hyperpigmentation. Associated with pregnancy or oral contraceptive pill use.
Antioxidants like vitamin C not only brighten skin, but also block the formation of an enzyme in the skin called tyrosinase, according to Ilyas, which triggers skin pigmentation.

Amelanism (also known as amelanosis) is a pigmentation abnormality characterized by the lack of pigments called melanins, commonly associated with a genetic loss of tyrosinase function. Amelanism can affect fish, amphibians, reptiles, birds, and mammals including humans. The appearance of an amelanistic animal depends on the remaining non ...
Tranexamic acid, azelaic acid and vitamin C all function as tyrosinase inhibitors, meaning that, as with kojic acid, they prevent the formation of an enzyme that’s critical for the pigment ...
