Predicted to enable beta-galactoside alpha-2,3-sialyltransferase activity. Predicted to be involved in glycolipid metabolic process; oligosaccharide metabolic process; and protein glycosylation. Predicted to be located in Golgi apparatus and membrane. Predicted to be integral component of membrane. Is expressed in early tubule. Orthologous to human ST3GAL6 (ST3 beta-galactoside alpha-2,3-sialyltransferase 6). [provided by Alliance of Genome Resources, Apr 2022]
