Alpha‐Synuclein Promotes Anterograde Vesicle Transport in Melanocytes and Melanoma Cells: A Pro‐Survival Function

Journal of the Chinese Chemical Society, EarlyView.
Model for how α‐syn modulates the positioning of endolysosomes in melanoma cells. (a) α‐syn tethers endolysosomes to the plasma membrane, a last step in anterograde transport. (b) Loss of α‐syn expression causes the loss of the tethering function, which leads to perinuclear vesicle clustering. Reproduced from the open access article.
