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).1 Publication2 Publications

    <p>This subsection of the 'Sequence' section provides information on polymorphic variants. If the variant is associated with a disease state, the description of the latter can be found in the <a href="http://www.uniprot.org/manual/involvement%5Fin%5Fdisease">'Involvement in disease'</a> subsection.<p><a href='/help/polymorphism' target='_top'>More...</a></p>Polymorphismi

    Genetic variation in A4GALT is responsible for the P1PK system blood group phenotypes [MIMi:111400]. Different combinations or absence of the P blood group system antigens define 5 different phenotypes: P1, P2, P1(k), P2(k), and p. Genetic variation in A4GALT determines the p phenotype, which is rare and does not express any antigens. It is also known as null phenotype; p individuals have antibodies against P, P1 and Pk antigens in their sera. These antibodies are clinically important because they can cause severe transfusion reactions and miscarriage (PubMed:10993874, PubMed:11896312). Genetic variation in A4GALT is also responsible for the NOR polyagglutination syndrome [MIMi:111400]. Polyagglutination is the occurrence of red cell agglutination by virtually all human sera, but not by autologous serum or sera from newborns, creating a risk of complications during transfusions of NOR erythrocytes. It is caused by the unusual Gal(alpha1-4)GalNAc glycolipid epitope (PubMed:22965229).3 Publications
