Summaries for ST6GALNAC3 Gene

Entrez Gene Summary for ST6GALNAC3 Gene

  • ST6GALNAC3 belongs to a family of sialyltransferases that transfer sialic acids from CMP-sialic acid to terminal positions of carbohydrate groups in glycoproteins and glycolipids (Lee et al., 1999 [PubMed 10207017]).[supplied by OMIM, Mar 2008]

GeneCards Summary for ST6GALNAC3 Gene

ST6GALNAC3 (ST6 N-Acetylgalactosaminide Alpha-2,6-Sialyltransferase 3) is a Protein Coding gene. Among its related pathways are Metabolism of proteins and Transport to the Golgi and subsequent modification. Gene Ontology (GO) annotations related to this gene include sialyltransferase activity. An important paralog of this gene is ST6GALNAC4.

UniProtKB/Swiss-Prot for ST6GALNAC3 Gene

  • Involved in the biosynthesis of ganglioside GD1A from GM1B. Transfers CMP-NeuAc with an alpha-2,6-linkage to GalNAc residue on NeuAc-alpha-2,3-Gal-beta-1,3-GalNAc of glycoproteins and glycolipids. ST6GalNAcIII prefers glycolipids to glycoproteins (By similarity).
