Background: ST3GAL6

Sialyltransferases add sialic acid to glycoproteins or glycosphingolipids and play important roles in many biological processes including immune recognition, pathogen infection, and cell adhesion (1). ST3GAL6 is an alpha2,3-sialyltransferase and forms alpha2-3 linked sialic acid on Gal-beta 1,4-GlcNAc structure on glycoproteins and glycolipids (2). This enzyme has high specificity for some gangliosides and glycoproteins and may contribute to the formation of sialyl Lewis x (sLex), a carbohydrate important for cell-to-cell recognition and a blood group antigen (3). Study on various alpha2,3-sialyltransferases indicate that ST3GAL6 selectively sialylates EGFR therefore affects ERK and AKT signal transduction pathways and positively correlates to cell proliferation and colony formation, which is in sharp contrast to ST3GAL4 that selectively sialylates beta1 integrin (4).
