Function
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 appearance within of distinct fibrillar structures. Release of the soluble form, ME20-S, could protect tumor cells from antibody mediated immunity.
The results of the present work demonstrate that the essential melanocyte-specific transcription factor MITF regulates expression of the genes encoding the melanoma tumor markers MLANA and SILV. MITF up- or down-regulation is seen to correspondingly modulate expression of MLANA and SILV in parallel directions, at both mRNA and protein levels.
