Predicted to enable N-acetyllactosamine synthase activity and UDP-galactose:glucosylceramide beta-1,4-galactosyltransferase activity. Predicted to be involved in several processes, including ganglioside biosynthetic process via lactosylceramide; neurogenesis; and positive regulation of embryonic development. Predicted to act upstream of or within poly-N-acetyllactosamine biosynthetic process. Predicted to be located in Golgi cisterna membrane. Predicted to be integral component of membrane. Predicted to be active in Golgi apparatus. Orthologous to human B4GALT5 (beta-1,4-galactosyltransferase 5). [provided by Alliance of Genome Resources, Apr 2022]
