  • ST6GALNAC6 belongs to a family of sialyltransferases that modify proteins and ceramides on the cell surface to alter cell-cell or cell-extracellular matrix interactions (Tsuchida et al., 2003 [PubMed 12668675]).[supplied by OMIM, Mar 2008]

GeneCards Summary for ST6GALNAC6 Gene

ST6GALNAC6 (ST6 (Alpha-N-Acetyl-Neuraminyl-2,3-Beta-Galactosyl-1,3)-N-Acetylgalactosaminide Alpha-2,6-Sialyltransferase 6) is a Protein Coding gene. Among its related pathways are Metabolism and Glycosphingolipid biosynthesis - ganglio series. GO annotations related to this gene include sialyltransferase activity and alpha-N-acetylgalactosaminide alpha-2,6-sialyltransferase activity. An important paralog of this gene is ST6GAL1.

UniProtKB/Swiss-Prot for ST6GALNAC6 Gene

  • Alpha-2,6-sialyltransferase involved in the synthesis of alpha-series gangliosides. Has activity toward GD1a, GT1b and GM1b. Has no activity toward glycoproteins. Responsible for the biosynthesis of DSGG (disialylgalactosylgloboside) from MSGG (monosialylgalactosylgloboside) in normal and malignant kidney. Participates in the synthesis of disialyl Lewis a (Le(a)).

    • The carbohydrate antigen disialyl Lewis a, which is at least partly synthesized by ST6GALNAC6, is a normal counterpart of sialyl Lewis a, better known as CA19-9, an antigen widely used as a serum marker for diagnosis of cancers in the digestive track. Disialyl Lewis a is predominantly expressed in non-malignant epithelial cells of the digestive organs, while sialyl Lewis a is preferentially expressed in cancers. Disialyl Lewis a in normal epithelial cells serves as a ligand for immunosuppressive receptors, such as SIGLEC7 and SIGLEC9, expressed on resident monocytes/macrophages and maintains immunological homeostasis of mucosal membranes in digestive organs. Sialyl Lewis a, as well as its positional isomer sialyl Lewis x, serves as a ligand for vascular cell adhesion molecule E-selectin and facilitates hematogenous metastasis through mediating adhesion of circulating cancer cells to vascular endothelium (PubMed:17760270).
