The protein encoded by this gene catalyzes the transfer of galactose to lactosylceramide to form globotriaosylceramide, which has been identified as the P(k) antigen of the P blood group system. This protein, a type II membrane protein found in the Golgi, is also required for the synthesis of the bacterial verotoxins receptor. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Dec 2015]
GeneCards Summary for A4GALT Gene
A4GALT (Alpha 1,4-Galactosyltransferase (P Blood Group)) is a Protein Coding gene. Diseases associated with A4GALT include Blood Group, P1pk System and Caffey Disease. Among its related pathways are Globo Sphingolipid Metabolism and Glycosphingolipid biosynthesis - lacto and neolacto series. Gene Ontology (GO) annotations related to this gene include galactosyltransferase activity and lactosylceramide 4-alpha-galactosyltransferase activity. An important paralog of this gene is A4GNT.
UniProtKB/Swiss-Prot Summary for A4GALT Gene
Catalyzes the transfer of galactose from UDP-alpha-D-galactose to lactosylceramide/beta-D-galactosyl-(1->4)-beta-D-glucosyl-(1<->1)-ceramide(d18:1(4E)) to produce globotriaosylceramide/globoside Gb3Cer (d18:1(4E)) (PubMed:10748143). Also able to transfer galactose to galactosylceramide/beta-D-Gal-(1<->1')-Cer (PubMed:10748143). Globoside Gb3Cer is a glycosphingolipid of the globo serie, one of the major types of neutral root structures of glycosphingolipids, that constitute a significant portion of mammalian cell membranes (Probable). Globotriaosylceramide/globoside Gb3Cer in blood and tissue cell membranes is the antigen Pk of blood histogroup P (PubMed:10747952).
(Microbial infection) Globotriaosylceramide is one of the cellular ligands for bacterial verotoxins.
