    SUBCELLULAR LOCALIZATION     plasma membrane
    text in the melanosome membrane (Guedj 2008)
    basic FUNCTION
  • regulation of melanogenesis
  • may be transporting substances required for melanin biosynthesis
  • playing a crucial role in the processing and intracellular trafficking of tyrosinse as well as other melanosomal proteins
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS endocytosis transport
