In addition, the colocalization between PAP and snapin in prostate cancer cells occurs in the cell lamellipodia [3], and it has been described that the lamellipodium is the site where exocytosis occurs in migrating mammalian cells [40], [41], supporting the hypothesis that colocalization of these proteins in the neuron will not happen in the cell soma. The gene discussed is ACP3; the disease is Familial prostate cancer.
