Predicted to enable O-fucosylpeptide 3-beta-N-acetylglucosaminyltransferase activity. Predicted to be involved in lymphocyte differentiation; negative regulation of Notch signaling pathway involved in somitogenesis; and somitogenesis. Predicted to act upstream of or within several processes, including compartment pattern specification; positive regulation of Notch signaling pathway; and regulation of somitogenesis. Predicted to be integral component of Golgi membrane. Human ortholog(s) of this gene implicated in spondylocostal dysostosis. Orthologous to human LFNG (LFNG O-fucosylpeptide 3-beta-N-acetylglucosaminyltransferase). [provided by Alliance of Genome Resources, Apr 2022]
