Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables beta-galactoside (CMP) alpha-2,3-sialyltransferase activity. Involved in ganglioside biosynthetic process via lactosylceramide. Acts upstream of or within protein glycosylation. Predicted to be located in Golgi membrane. Predicted to be active in membrane. Is expressed in several structures, including exocrine gland; genitourinary system; hemolymphoid system gland; intestine; and liver. Orthologous to human ST3GAL2 (ST3 beta-galactoside alpha-2,3-sialyltransferase 2).
