MITF (Melanocyte Inducing Transcription Factor): MITF is a key regulator that highlights its role in the development and function of melanocytes, the cells responsible for pigment production. It is essential for normal pigmentation, and mutations in MITF can result in pigmentary disorders and increase the risk of melanoma, a form of skin cancer. MITF also plays a role in the development of certain retinal cells and is associated with Waardenburg syndrome.
