    basic FUNCTION
  • recognized by T-lymphocytes of patients with melanoma
  • required for the function of the melanosomal matrix protein SILV and the maturation of melanosomes
  • integral membrane melanosomal protein that has been shown to form complexes with SILV and has been suggested to control SILV processing and stability (Giordano 2009)
  • similar to GPR143, regulates melanosome maturation and in particular the maintenance of melanosomal identity and composition (Giordano 2009)

  • complex with SILV
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • interacting with SILV (indispensable for SILV function and thus plays an important role in regulating mammalian pigmentation)
  • interacting with GPR143 early during its biosynthetic pathway acting as an escort protein that helps its stabilization and prevents degradation(Giordano 2009)
  • interacting with SILV (Giordano 2009)
