Melanocytes phagocytize melanin. First, melanocytes which are present in the lowest or basal layer of the epidermis, produce the pigment melanin. The melanin forms granules called melanosomes. After the keratinocytes take up the pigment, it clusters around the keratinocyte nucleus on the superficial side. This protects the DNA in the keratinocyte nucleus from damage due to UV radiation.
