Predicted to enable acetylglucosaminyltransferase activity. Predicted to be involved in poly-N-acetyllactosamine biosynthetic process. Predicted to act upstream of or within protein glycosylation. Predicted to be located in Golgi apparatus and membrane. Predicted to be integral component of membrane. Predicted to be active in Golgi membrane. Is expressed in several structures, including alimentary system; brain; genitourinary system; respiratory system; and sensory organ. Orthologous to human B3GNT7 (UDP-GlcNAc:betaGal beta-1,3-N-acetylglucosaminyltransferase 7). [provided by Alliance of Genome Resources, Apr 2022]
