Predicted to enable acetylgalactosaminyltransferase activity. Predicted to be involved in UDP-N-acetylgalactosamine metabolic process and negative regulation of cell-cell adhesion. Predicted to act upstream of or within UDP-N-acetylglucosamine metabolic process and protein glycosylation. Orthologous to human B4GALNT2 (beta-1,4-N-acetyl-galactosaminyltransferase 2).
