Melanocyte protein PMEL (PMEL)

Plays a central role in the biogenesis of melanosomes. Involved in the maturation of melanosomes from stage I to II.

The transition from stage I melanosomes to stage II melanosomes involves an elongation of the vesicle, and the look within of different fibrillar structures. Release of the soluble form, ME20-S, could protect tumor cells from antibody mediated immunity.
