Predicted to enable alpha-N-acetylgalactosaminide alpha-2,6-sialyltransferase activity. Predicted to be involved in protein glycosylation and sialylation. Predicted to act upstream of or within oligosaccharide biosynthetic process. Predicted to be located in Golgi apparatus. Predicted to be integral component of membrane. Orthologous to human ST6GALNAC1 (ST6 N-acetylgalactosaminide alpha-2,6-sialyltransferase 1). [provided by Alliance of Genome Resources, Apr 2022]
