MCAM and melanoma: Recent literature suggests that MUC18 can be glycosylated via N-acetyl-glucosaminyltransferease III and V without a role in migration [18] or could be glycosylated and stabilized by β-1,3-galactosyl-O-glycosyl-glycoprotein β-1,6-N-acetylglucosaminyltransferase 3 (GCNT3) playing a major role in melanoma migration and invasion [19].
