Summaries for C1GALT1 Gene

Entrez Gene Summary for C1GALT1 Gene

  • The protein encoded by this gene generates the common core 1 O-glycan structure, Gal-beta-1-3GalNAc-R, by the transfer of Gal from UDP-Gal to GalNAc-alpha-1-R. Core 1 is a precursor for many extended mucin-type O-glycans on cell surface and secreted glycoproteins. Studies in mice suggest that this gene plays a key role in thrombopoiesis and kidney homeostasis.[provided by RefSeq, Sep 2010]

GeneCards Summary for C1GALT1 Gene

C1GALT1 (Core 1 Synthase, Glycoprotein-N-Acetylgalactosamine 3-Beta-Galactosyltransferase 1) is a Protein Coding gene. Diseases associated with C1GALT1 include Iga Glomerulonephritis and Hypersensitivity Vasculitis. Among its related pathways are Mucin type O-glycan biosynthesis and O-linked glycosylation. GO annotations related to this gene include transferase activity, transferring glycosyl groups and glycoprotein-N-acetylgalactosamine 3-beta-galactosyltransferase activity. An important paralog of this gene is C1GALT1C1.

UniProtKB/Swiss-Prot for C1GALT1 Gene

  • Glycosyltransferase that generates the core 1 O-glycan Gal-beta1-3GalNAc-alpha1-Ser/Thr (T antigen), which is a precursor for many extended O-glycans in glycoproteins. Plays a central role in many processes, such as angiogenesis, thrombopoiesis and kidney homeostasis development.
