Predicted to enable alpha-N-acetylgalactosaminide alpha-2,6-sialyltransferase activity. Predicted to be involved in protein O-linked glycosylation and protein sialylation. Predicted to be located in Golgi apparatus and membrane. Predicted to be integral component of membrane. Is expressed in several structures, including alimentary system; genitourinary system; hemolymphoid system gland; lung; and mammary gland. Orthologous to human ST6GALNAC2 (ST6 N-acetylgalactosaminide alpha-2,6-sialyltransferase 2). [provided by Alliance of Genome Resources, Apr 2022]
