Predicted to enable N-acetyllactosaminide beta-1,3-N-acetylglucosaminyltransferase activity. Acts upstream of or within several processes, including axon guidance; cellular response to leukemia inhibitory factor; and sensory perception of smell. 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; immune system; and nose. Orthologous to human B3GNT2 (UDP-GlcNAc:betaGal beta-1,3-N-acetylglucosaminyltransferase 2). [provided by Alliance of Genome Resources, Apr 2022]
