Enables glycoprotein-fucosylgalactoside alpha-N-acetylgalactosaminyltransferase activity. Involved in defense response to bacterium. Predicted to be located in Golgi cisterna membrane and extracellular region. Predicted to be active in Golgi apparatus and vesicle. Human ortholog(s) of this gene implicated in several diseases, including Plasmodium falciparum malaria; graft-versus-host disease; 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); INTERACTS WITH 17beta-estradiol; alpha-Zearalanol; fenvalerate.

Rat encodes the paralogous gene equivalent of the human histo-blood group ABO gene. Association with antigen expression by overexpression of human ABO transferase.
Blood group A glycosyltransferase occurring as alleles with high sequence difference is transiently induced during a Nippostrongylus brasiliensis parasite infection.
A antigen expressesd in tongue, oesophagus, large intestine, pancreas, parotid gland, submaxillary gland stomach, seminal vesicle, parathyroid gland, and thymus
