Predicted to enable N-acetyllactosaminide beta-1,6-N-acetylglucosaminyltransferase activity. Predicted to be involved in several processes, including maintenance of lens transparency; positive regulation of heterotypic cell-cell adhesion; and positive regulation of intracellular signal transduction. Predicted to be located in Golgi apparatus. Human ortholog(s) of this gene implicated in cataract and cataract 13 with adult i phenotype. Orthologous to human GCNT2 (glucosaminyl (N-acetyl) transferase 2 (I blood group)). [provided by Alliance of Genome Resources, Apr 2022]
