Layered Cells: The skin, the largest organ in the human body, consists of three layers: epidermis (outer), dermis (middle), and subcutis (lower). Melanin, the pigment produced by the melanocytes in the basal layer of the epidermis, has a protective function. The skin is composed of two major layers: a superficial epidermis and a deeper dermis. Differently expressed genes lead to different proteins made in the cell, which leads to different morphology, shape or function. Skin cells have different functional roles in their respective regions-the basal cell layer is the innermost layer of the epidermis, containing the keratinocytes and melanocytes. 7 Melanin is produced from l-tyrosine (L-Tyr) with the aid of enzymatic reactions by tyrosinase (Tyr), Tyr-related protein (Tyrp)-1, and Tyrp2.
