Enables fucosylgalactoside 3-alpha-galactosyltransferase activity and glycoprotein-fucosylgalactoside alpha-N-acetylgalactosaminyltransferase activity. Predicted to be involved in lipid glycosylation. Predicted to be located in cytoplasmic vesicle. Predicted to be active in Golgi apparatus and vesicle. Is expressed in alimentary system; male reproductive gland or organ; and spleen. Human ortholog(s) of this gene implicated in several diseases, including Plasmodium falciparum malaria; gallbladder carcinoma; leukemia (multiple); lung disease (multiple); and severe acute respiratory syndrome. Orthologous to human ABO (ABO, alpha 1-3-N-acetylgalactosaminyltransferase and alpha 1-3-galactosyltransferase). [provided by Alliance of Genome Resources, Apr 2022]
