Summaries for C1GALT1C1 Gene

Entrez Gene Summary for C1GALT1C1 Gene

  • This gene encodes a type II transmembrane protein that is similar to the core 1 beta1,3-galactosyltransferase 1, which catalyzes the synthesis of the core-1 structure, also known as Thomsen-Friedenreich antigen, on O-linked glycans. This gene product lacks the galactosyltransferase activity itself, but instead acts as a molecular chaperone required for the folding, stability and full activity of the core 1 beta1,3-galactosyltransferase 1. Mutations in this gene have been associated with Tn syndrome. Alternatively spliced transcript variants encoding the same protein have been identified. [provided by RefSeq, Dec 2009]

GeneCards Summary for C1GALT1C1 Gene

C1GALT1C1 (C1GALT1 Specific Chaperone 1) is a Protein Coding gene. Diseases associated with C1GALT1C1 include Tn Polyagglutination Syndrome, Somatic and Wound Botulism. Among its related pathways are Metabolism of proteins and Mucin type O-glycan biosynthesis. GO annotations related to this gene include polypeptide N-acetylgalactosaminyltransferase activity. An important paralog of this gene is C1GALT1C1L.

UniProtKB/Swiss-Prot for C1GALT1C1 Gene

  • Probable chaperone required for the generation of 1 O-glycan Gal-beta1-3GalNAc-alpha1-Ser/Thr (T antigen), which is a precursor for many extended O-glycans in glycoproteins. Probably acts as a specific molecular chaperone assisting the folding/stability of core 1 beta-3-galactosyltransferase (C1GALT1).

    • Associates with core 1 beta-3-galactosyltransferase (C1GALT1), probably not with the soluble active form.
    • Defects in C1GALT1C1 in Ag104A cell line create a tumor-specific glycopeptidic neo-epitope. This epitope induces a high-affinity, highly specific, syngeneic monoclonal antibody. This is caused by the abolition of function of a glycosyltransferase, disrupting O-glycan Core 1 synthesis.

  • Tn polyagglutination syndrome (TNPS) [MIM:300622]: A clonal disorder characterized by the polyagglutination of red blood cells by naturally occurring anti-Tn antibodies following exposure of the Tn antigen on the surface of erythrocytes. Only a subset of red cells express the antigen, which can also be expressed on platelets and leukocytes. This condition may occur in healthy individuals who manifest asymptomatic anemia, leukopenia, or thrombocytopenia. However, there is also an association between the Tn antigen and leukemia or myelodysplastic disorders. {ECO:0000269 PubMed:16251947, ECO:0000269 PubMed:18537974}.
