Predicted to enable alpha-N-acetylgalactosaminide alpha-2,6-sialyltransferase activity. Predicted to be involved in ceramide metabolic process; oligosaccharide metabolic process; and protein glycosylation. Predicted to be located in nucleoplasm. Is expressed in several structures, including genitourinary system; hemolymphoid system gland; lung; mammary gland; and nervous system. Orthologous to human ST6GALNAC3 (ST6 N-acetylgalactosaminide alpha-2,6-sialyltransferase 3). [provided by Alliance of Genome Resources, Apr 2022]
