Predicted to enable acetylglucosaminyltransferase activity and protein O-GlcNAc transferase activity. Involved in neuron migration and protein O-linked mannosylation. Predicted to be located in membrane. Predicted to be integral component of membrane. Predicted to be active in endoplasmic reticulum. Is expressed in brain and eye. Human ortholog(s) of this gene implicated in congenital muscular dystrophy-dystroglycanopathy type A8. Orthologous to human POMGNT2 (protein O-linked mannose N-acetylglucosaminyltransferase 2 (beta 1,4-)). [provided by Alliance of Genome Resources, Apr 2022]
